Use of a low-cost biosorbent to remove pesticides from wastewater.

摘要: A lignocellulosic substrate (LS) obtained from our local agroindustry was used as a low-cost and effective adsorbent for the removal of pesticides wastewaters. The studied were terbumeton (N-(1,1-dimethyl)-Nethyl-6-methoxy-1,3,5-triazine-2,4-diamine), desethyl (N-(1,1-dimethylethyl)-6-methoxy-1,3,5-triazine-2,4-diamine), dimetomorph (4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)acryloyl]morpholine), isoproturon (3-(4-isopropylphenyl)-1,1-dimethylurea). Batch column experiments conducted function pH pesticide concentration under laboratory industrial conditions. range varied 2 x 10(-7) to 3 10(-4) mol L(-1). influence organic inorganic pollutants assessed by studying retention in presence copper(II) surfactant. These indicated that LS is an efficient toward investigated has little other pollutants. kinetic adsorptions are fast, amounts adsorbed 1 8 g kg(-1) LS. capacities show can provide simple, effective, cheap method removing contaminated waters. Thus, this biomaterial may be useful cleaning up polluted
