The same methodology of extraction was applied to cork, for comparative purposes. Eighteen phenolic compounds were identified in cork, five of them are reported for the first time as its constituents. Sixteen and thirteen phenolic compounds were identified as cork powder and black condensate components, respectively, with only one compound of each residue published before as its constituent. The antioxidant activity of the extracts was evaluated, being, to our knowledge, the first study concerning the antioxidant activity of these cork residues. The extracts present an antioxidant activity higher than BHT, with black condensate showing the lowest IC50 value. These results, together with the phenolic content values, demonstrate the high potential of these residues as source of high value compounds.</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%">Pintor, Ariana M A</style></author><author><style face="normal" font="default" size="100%">Ferreira, Catarina I A</style></author><author><style face="normal" font="default" size="100%">Pereira, Joana C</style></author><author><style face="normal" font="default" size="100%">Correia, Patrícia</style></author><author><style face="normal" font="default" size="100%">Silva, Susana P</style></author><author><style face="normal" font="default" size="100%">Vilar, Vítor J P</style></author><author><style face="normal" font="default" size="100%">Botelho, Cidália M S</style></author><author><style face="normal" font="default" size="100%">Boaventura, Rui A R</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Use of cork powder and granules for the adsorption of pollutants: a review.</style></title><secondary-title><style face="normal" font="default" size="100%">Water research</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">activated carbon</style></keyword><keyword><style  face="normal" font="default" size="100%">Adsorption</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork granules</style></keyword><keyword><style  face="normal" font="default" size="100%">cork powder</style></keyword><keyword><style  face="normal" font="default" size="100%">Heavy metals</style></keyword><keyword><style  face="normal" font="default" size="100%">Pollutants</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year></dates><volume><style face="normal" font="default" size="100%">46</style></volume><pages><style face="normal" font="default" size="100%">3152-3166</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Cork powder and granules are the major subproducts of the cork industry, one of the leading economic activities in Portugal and other Mediterranean countries. Many applications have been envisaged for this product, from cork stoppers passing through the incorporation in agglomerates and briquettes to the use as an adsorbent in the treatment of gaseous emissions, waters and wastewaters. This paper aims at reviewing the state of the art on the properties of cork and cork powder and their application in adsorption technologies. Cork biomass has been used on its original form as biosorbent for heavy metals and oils, and is also a precursor of activated carbons for the removal of emerging organic pollutants in water and VOCs in the gas phase. Through this literature review, different potential lines of research not yet explored can be more easily identified.</style></abstract><accession-num><style face="normal" font="default" size="100%">22534120</style></accession-num></record></records></xml>
