Use of Biopolymeric Membranes for Adsorption of Paraquat Herbicide from Water
(Springer, 2012-07-01)
The use of membranes prepared with alginate and chitosan to adsorb paraquat aqueous solution was evaluated as a potential alternative technique for remediation of contaminated water. Production of bilayer membranes was ...

Chitosan and alginate biopolymer membranes for remediation of contaminated water with herbicides
(Elsevier B.V., 2013-12-15)
This study investigated the adsorption behavior of the herbicides diquat, difenzoquat and clomazone on biopolymer membranes prepared with alginate and chitosan (pristine and multi-layer model) for contaminated water ...
Utilização de sílica mesoporosa magnética para remoção de bário contido em água
(Universidade Tecnológica Federal do ParanáMedianeiraBrasilLicenciatura em QuímicaUTFPR, 2016-12-01)
Due to population and industrial growth, a greater use of water is necessary and, as a consequence, there is a greater insertion of waste discarded inadequately. As a result, metal ions, such as barium contaminants, are ...
Adsorption of Cd (II), Pb (II) and Cr (III) on chemically modified Euterpe Oleracea biomass for the remediation of water pollution
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAO, 2021)
This study evaluated the use of Euterpe oleracea endocarp after chemical modification with H2O2, H2SO4 and NaOH for the removal of Cd2+, Pb2+ and Cr3+ from water. Therefore, the adsorbent was characterized for its chemical ...
Adsorptive properties of silica gel for biodiesel refining
(American Chemical Society, 2008-11)
The refining of biodiesel by adsorption over silica gel was assessed. Silica gel samples were used for the adsorption of glycerol and monoglycerides. Room-temperature isotherms for the adsorption of glycerol were measured ...
Application of Natural Organic Residues as Adsorbents to Remove Lead from Waters
(2019-08-01)
The contamination of the environment by potentially toxic metals is highlighted by possible impacts of their high availability. Thus, the development of alternative absorbents that can be used in the remediation of ...
Removal of organic contaminants from a synthetic oilfield produced water by adsorption process using vegetable and bone bovine activated carbons
(ASSOCIAÇÃO BRASILEIRA DE PETRÓLEO E GÁS - ABPG, 2019-10-08)
