Samples with different textural (microporosity/ micro + mesoporosity) and surface chemistry (acidic/basic) were obtained. In the best compromise between porosity development/preparation yield, apparent surface areas P900m2 g?1 were attained. Selected samples were assayed as adsorbents for the removal of pharmaceutical compounds (ibuprofen, paracetamol, acetylsalicylic acid, clofibric acid, caffeine and iopamidol). Kinetic results show that the steam activated carbon removes all the pharmaceutical compounds under study with removal efficien- cies between 40% and 90%. Ibuprofen equilibrium adsorption isotherms showed that sample chemically activated with KOH at 800 ?C presents higher adsorption capacity (174.4 mg g?1) and affinity for this target molecule than the steam activated and commercial samples. The overall results reveal that the lab-made carbons have adequate properties for pharmaceutical compounds removal, the results compar- ing favourably to those obtained with samples commercialized for water treatment purposes</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%">Atanes, E</style></author><author><style face="normal" font="default" size="100%">Nieto-Márquez, A</style></author><author><style face="normal" font="default" size="100%">Cambra, A</style></author><author><style face="normal" font="default" size="100%">Ruiz-Pérez, M C</style></author><author><style face="normal" font="default" size="100%">Fernández-Martínez, F</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Adsorption of SO2 onto waste cork powder-derived activated carbons</style></title><secondary-title><style face="normal" font="default" size="100%">Chemical Engineering Journal</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%">Cork</style></keyword><keyword><style  face="normal" font="default" size="100%">Porosity</style></keyword><keyword><style  face="normal" font="default" size="100%">SO2 adsorption</style></keyword><keyword><style  face="normal" font="default" size="100%">Surface acidity</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year></dates><publisher><style face="normal" font="default" size="100%">Elsevier B.V.</style></publisher><volume><style face="normal" font="default" size="100%">211-212</style></volume><pages><style face="normal" font="default" size="100%">60-67</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Three activated carbon samples have been prepared by thermal (ACchar ), physical (with CO2, ACCO2) and chemical (with KOH, ACKOH) activation of waste cork powder. Cork was characterized by thermogravimetric, elemental and proximate analyses, and activated carbons were characterized by elemental and proximate analyses, adsorption–desorption of N2, acid/base and Boehm’s titration and FTIR (ATR) spectroscopy. A commercial activated carbon sample (ACcom) was subjected to the same characterization program for comparison purposes. Activation of cork conducted to an increase in BET surface area and pore volume in the sequence: ACchar &lt; ACCO2 &lt; ACKOH, getting close to those of ACcom, and to an increase in surface acidity in the sequence: ACchar &lt; ACCO2 ACcom &lt; ACKOH. The four adsorbents were tested in the adsorption of SO2, where ACKOH presented the highest adsorption capacity, while ACchar and ACCO2 presented similar behaviors, comparable to that of ACcom. Adsorption equilibrium was successfully ﬁtted to Langmuir and Freundlich isotherms. Desorption experiments demonstrated how SO2 strong adsorption was favored when decreasing surface acidity.</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><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%">Carrott, P.

It is shown that cork is a versatile precursor and allows us to prepare a wide variety of materials with quite different pore structural characteristics by precise control of the impregnation and pyrolysis conditions. Even under relatively mild conditions, it was possible to produce cork based carbons with high pore volumes, in the range 0.5–0.7 cm 3 g 1 , and to simultaneously control the mean pore width over a three-fold range from a value as low as 0.7 nm up to a value as high as 2.2 nm. The best materials produced present pore structural characteristics which are signiﬁcantly different to the vast majority of commercial activated carbons. In particular, the possibility of obtaining such high pore volumes in essentially microporous materials, containing virtually no mesoporosity in most cases, is noteworthy.
