摘　　要：研究了玉米秸秆生物质炭对水中杀扑磷的吸附去除,并讨论了玉米秸秆生物质炭投加量、pH值、吸附时间对去除效果的影响。确定了最佳吸附条件为20mL水样中,玉米秸秆生物炭投加量为0.6g,pH值为6.5,吸附20min能有效去除水中的杀扑磷。结果表明,玉米秸秆生物炭对水中杀扑磷农药具有较好的去除效果,去除率达91%。The adsorption of methidathion on the maize straw-biochar adsorbent was studied.Effect of absorbing time,pH and adsorbent dose were investigated on removal of malathion.The experimental results showed that the target analytes can be removed,and the conditions as follows:sample solution volume was 20 mL,the adsorbent dosage was 0.6 g,the pH of water sample was adjusted 6.5,adsorption equilibrium time was 20 min.The results showed that maize straw biochar had good removal effect on methidathion in water sample,and the removal rate was 91%.
