“…Based on the elemental analysis (Table 2), the values of the CHO content in the BGS biomass (H/C ratio 0.13) are very similar to the results of the elemental CHO analysis of other studies, which report the content in various agricultural wastes from 42-59% for C, 3-7% for H and 32-50% for O [20,36]. As expected, the unmodified BGS had no nitrogen in its compositions.…”

“…The comparative analysis of the chemical composition of different agricultural waste, tested for anion sorption (pecan shells, peanut shells, almond shells, cotton seed hulls, rice hulls, sugarcane bagasse, corn cob, corn stover, oat hulls, oak chips, rice straw, soybean hulls), shows that BGS is most similar to almond, peanut and pecan shells, considering a high lignin content (between 27 and 48%), and the similar content of other constituents [36]. However, one should bear in mind the fact that even the same biomass, but of different natural origin and sites have a very different composition (e.g.…”

“…[4][5][6][7][8][9][10][11] Além dos materiais contendo ferro, uma série de outros materiais também tem sido utilizada na adsorção de arsênio como, por exemplo, zeolitas, 2 pasta de cimento Portland, 12 oxisol, 13 políme-ros contendo zircônio (IV), 14 cinzas, 15 sub-produtos da atividade agrícola. 16 Dentre estes materiais alternativos utilizados na adsorção de arsênio encontram-se a quitina e quitosana 17,18 e quitosana impregnada com íons molibdato. 19,20 Por outro lado, em estudos anteriores mostramos que complexos de quitosana com íons Fe 3+ , na forma insolúvel, apresentam grande capacidade de adsorção de oxianions como, por exemplo, fosfato 21,22 e cromato.…”

“…Various quaternizing reagents have been tested for this purpose, e.g. dimethylamine (Anirudhan et al 2006); urea (Benyoucef and Amrani 2011;Karachalios 2012); 2-hidroxypropyltrimethyl ammonium chloride (De Lima et al 2012); polyallylamine hydrochloride ); trimethylammoniumchloride (Marshall and Wartelle 2004;Wartelle and Marshall 2006); ethylenediamine & triethylamine Yue et al 2010;Xu et al 2011a), etc. In most cases, quaternized AWBs exhibited the enhanced adsorption capacities for PO4 3-as compared to raw AWBs.…”
