Release of poorly treated industrial wastewater containing pesticides has adverse effect on aquatic environment. In this study, an attempt was made to evaluate the performance of biopolymer-nanoorganoclay composite based on carboxy methyl cellulose and two nanoorganobentonites viz. DMDA (nanobentonite modified with 35–45 wt% dimethyl dialkyl (C14–C18) amine) and ODAAPS (nanobentonite modified with 15–35 wt% octadecylamine and 0.5–5 wt% aminopropyltriethoxysilane) in the ratio 1:2.5:2.5 for removing nine pesticides, namely atrazine, butachlor, carbendazim, carbofuran, imidacloprid, isoproturon, pendimethalin, thiophanate methyl and thiamethoxam from aqueous solution. The composite dosage was optimized using Jar test in which aluminum sulfate (alum) was used as coagulation/flocculation aid. Decontamination efficiency of the composite was validated in pesticide industrial effluent. Decontamination process was found to be efficient in removing the selected pesticides from water (57–100%) as well as from industrial effluent (63–91%). The prepared composite was very efficient in removing more than 90% of butachlor, isoproturon, pendimethalin and thiophanate methyl from water. Spent or used composite was regenerated by acetone washing followed by thermal regeneration at 200 °C. The regenerated composite was able to maintain 57–97% of its initial pesticide removal efficiency even after second regeneration. Preparation and regeneration of the composite is easy and effective making the composite a promising adsorbent for pesticides.

释放处理不良的含农药工业废水会对水环境造成不利影响。在这项研究中，试图评估基于羧甲基纤维素和两种纳米有机膨润土的生物聚合物-纳米有机粘土复合材料的性能。DMDA（用35–45 wt％的二甲基二烷基（C14–C18）胺改性的纳米膨润土）和ODAAPS（用15–35 wt％的十八烷基胺和0.5–5 wt％的氨基丙基三乙氧基硅烷改性的纳米膨润土）可去除九种水溶液中的杀虫剂，包括at去津，丁草胺，多菌灵，呋喃丹，吡虫啉，异丙隆，戊二甲灵，甲基托布津和噻虫嗪。使用Jar试验（其中硫酸铝（铝）用作凝结/絮凝助剂）优化了复合剂量。在农药工业废水中验证了复合材料的去污效率。发现去污工艺可以有效地从水中（57-100％）和工业废水（63-91％）中去除选定的农药。所制备的复合材料非常有效地从水中去除了超过90％的丁草胺，异丙隆，二甲戊乐灵和甲基托布津。用过的或用过的复合材料通过丙酮洗涤再生，然后在200°C进行热再生。即使在第二次再生后，再生的复合材料仍能够保持其初始农药去除效率的57–97％。复合材料的制备和再生简单有效，使复合材料成为农药的有希望的吸附剂。发现去污工艺可以有效地从水中（57-100％）和工业废水（63-91％）中去除选定的农药。所制备的复合材料非常有效地从水中去除了超过90％的丁草胺，异丙隆，二甲戊乐灵和甲基托布津。用过的或用过的复合材料通过丙酮洗涤再生，然后在200°C进行热再生。即使在第二次再生后，再生的复合材料仍能够保持其初始农药去除效率的57–97％。复合材料的制备和再生简单有效，使复合材料成为农药的有希望的吸附剂。发现去污工艺可以有效地从水中（57-100％）和工业废水（63-91％）中去除选定的农药。所制备的复合材料非常有效地从水中去除了超过90％的丁草胺，异丙隆，二甲戊乐灵和甲基托布津。用过的或用过的复合材料通过丙酮洗涤再生，然后在200°C进行热再生。即使在第二次再生后，再生的复合材料仍能够保持其初始农药去除效率的57–97％。该复合物的制备和再生容易且有效，使得该复合物成为有前途的农药吸附剂。从水中加入二甲戊乐灵和甲基托布津。用过的或用过的复合材料通过丙酮洗涤再生，然后在200°C进行热再生。即使在第二次再生后，再生的复合材料仍能够保持其初始农药去除效率的57–97％。复合材料的制备和再生简单有效，使复合材料成为农药的有希望的吸附剂。从水中加入二甲戊乐灵和甲基托布津。用过的或用过的复合材料通过丙酮洗涤再生，然后在200°C进行热再生。即使在第二次再生后，再生的复合材料仍能够保持其初始农药去除效率的57–97％。复合材料的制备和再生简单有效，使复合材料成为农药的有希望的吸附剂。
