The aim of this study is to evaluate the efficiency extent of this method using a cork powder as biosorbent for Cr(VI). The Fourier Transform Infrared spectroscopy (FTIR) analysis permits to distinguish the type of functional groups likely to participate in metal binding. A linear form of BET isotherms for all the three used temperatures (i.e. 25, 35 and 45°C) and a pseudo-second-order equation of adsorption kinetics are obtained. Other experimental results highlight the meaningful influence of parameters such as contact time, pH, concentration of Cr(VI) and the adsorbent particle size on Cr(VI) adsorption . 97% of Cr(VI) has been removed under definite conditions particularly a particle size of diameter d &lt; 0.08 mm and pH of 2-3 values.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Nunes, L J R</style></author><author><style face="normal" font="default" size="100%">Matias, J C O</style></author><author><style face="normal" font="default" size="100%">Catalão, J P S</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Energy recovery from cork industrial waste: Production and characterisation of cork pellets</style></title><secondary-title><style face="normal" font="default" size="100%">Fuel</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork pellets</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork waste</style></keyword><keyword><style  face="normal" font="default" size="100%">Energy recovery</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year></dates><publisher><style face="normal" font="default" size="100%">Elsevier Ltd</style></publisher><pages><style face="normal" font="default" size="100%">1-7</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The cork industry presents itself as one of the most entrepreneurial in the Portuguese industrial sector, contributing significantly to the increase of exports. However, it is an industry in which the use of raw materials is maximised leaving a large volume of waste. The cork industry has tried to take advantage of these residues, mainly through direct energy recovery, despite the technical and safety difficulties pre- sented by the use of such low density material, which complicates and hinders its transportation for industrial uses outside the area in which it is produced. The densification process opens new doors for such use and also for its storage, because it produces better results when compared with other more com- mon products, such as wood sawdust or even forest and agricultural waste. Thus, cork pellets emerge as a safer and more easily transportable alternative for energy recovery from cork dust and other granulated types of cork waste, which offer the prospects for wider use. The results demonstrate that cork pellets have higher calorific value when compared with other biomass pellets; typically, approximately 20 MJ/ kg with 3% volume of ashes, which is equivalent to that obtained from the combustion of pellets pro- duced from combined forest and agricultural waste with a bulk density of 750 kg/m3, which offers real advantages in terms of logistics. </style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Olivella, Maria À</style></author><author><style face="normal" font="default" size="100%">Jové, Patrícia</style></author><author><style face="normal" font="default" size="100%">Oliveras, Anna</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The use of cork waste as a biosorbent for persistent organic pollutants–Study of adsorption/desorption of polycyclic aromatic hydrocarbons</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Environmental Science and Health, Part A</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Adsorption</style></keyword><keyword><style  face="normal" font="default" size="100%">Aromatic</style></keyword><keyword><style  face="normal" font="default" size="100%">Aromatic: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">biosorbent</style></keyword><keyword><style  face="normal" font="default" size="100%">Chemical</style></keyword><keyword><style  face="normal" font="default" size="100%">Chemical: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork waste</style></keyword><keyword><style  face="normal" font="default" size="100%">Environmental Remediation</style></keyword><keyword><style  face="normal" font="default" size="100%">Environmental Remediation: methods</style></keyword><keyword><style  face="normal" font="default" size="100%">Gas Chromatography-Mass Spectrometry</style></keyword><keyword><style  face="normal" font="default" size="100%">Lignin</style></keyword><keyword><style  face="normal" font="default" size="100%">Lignin: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids</style></keyword><keyword><style  face="normal" font="default" size="100%">Lipids: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">organic pollutants</style></keyword><keyword><style  face="normal" font="default" size="100%">PAHs</style></keyword><keyword><style  face="normal" font="default" size="100%">Polycyclic Hydrocarbons</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Solid Phase Microextraction</style></keyword><keyword><style  face="normal" font="default" size="100%">sorption-desorption</style></keyword><keyword><style  face="normal" font="default" size="100%">Time Factors</style></keyword><keyword><style  face="normal" font="default" size="100%">Water Pollutants</style></keyword><keyword><style  face="normal" font="default" size="100%">water treatment</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2011///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.tandfonline.com/doi/abs/10.1080/10934529.2011.579845http://www.ncbi.nlm.nih.gov/pubmed/21644164</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">46</style></volume><pages><style face="normal" font="default" size="100%">824 - 832</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The aim of this study is to determine the sorption-desorption behavior of a mixture of thirteen aqueous PAHs on cork waste at a particle of size 0.25?0.42 mm obtained from the remains of cork strips. The final purpose is to use this natural adsorbent as an alternative to activated carbon in an innovative approach for the removal of this class of toxic compounds, and significantly reduce the regeneration costs of the process. The chemical composition of the selected cork revealed that suberin (38.5 %) and lignin (31.6 %) were the main structural components of the cell wall. The high efficiency of cork as a biosorbent of PAHs is shown by the fact that just over 80 % of adsorption occurred during the first two minutes of contact time. Both Freundlich's and Langmuir's isotherms gave good fits to the sorption process. The highest adsorption affinities were exhibited for pyrene, anthracene, and phenanthrene. Desorption studies indicate a high degree of irreversibility for all PAHs, and especially so in the case of high molecular PAHs. The correlation with KF and low molecular weight PAHs was the most significant. The quantity of cork required to reduce water pollution was estimated to be between 3 and 15 times less than the quantities required in the case of other materials (i.e. aspen wood and leonardite). This study demonstrates for the first time that cork is a potential biosorbent for PAHs and may have relevance in the future treatment of PAH-contaminated waters.</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><notes><style face="normal" font="default" size="100%">From Duplicate 1 (The use of cork waste as a biosorbent for persistent organic pollutants–Study of adsorption/desorption of polycyclic aromatic hydrocarbons - Olivella, Maria À; Jové, Patrícia; Oliveras, Anna)From Duplicate 1 (The use of cork waste as a biosorbent for persistent organic pollutants–Study of adsorption/desorption of polycyclic aromatic hydrocarbons - Olivella, Maria À; Jové, Patrícia; Oliveras, Anna)The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Taylor &amp; Francis&lt;br/&gt;accession-num: 21644164</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Cabañas, Aracel</style></author><author><style face="normal" font="default" size="100%">Sáez, Felicia</style></author><author><style face="normal" font="default" size="100%">González, Alberto</style></author><author><style face="normal" font="default" size="100%">Escalada, Ricardo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Quantitative Assessment of Polycyclic Aromatic Hydrocarbons from Corkwaste Combustion Emissions</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Agricultural Engineering Research</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork waste</style></keyword><keyword><style  face="normal" font="default" size="100%">Fluidized bed combustion (PG)</style></keyword><keyword><style  face="normal" font="default" size="100%">GC-MS</style></keyword><keyword><style  face="normal" font="default" size="100%">Polycyclic aromatic hydrocarbons (PAHs)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2000</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2000///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0021863400905948</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">77</style></volume><pages><style face="normal" font="default" size="100%">349 - 354</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Cork is a natural raw material obtained from the cork oak (Quercus suber).
