摘要
采用玉米秸秆生物质炭为吸附剂对环境水中马拉硫磷进行吸附研究。考察了吸附剂用量、吸附时间、pH等因素对环境水中马拉硫磷农药去除率的影响。确定了最佳吸附条件:在20mL水样中,0.4g玉米秸秆生物炭为吸附剂,pH为5,30min吸附达平衡。结果表明玉米秸秆生物炭对环境水中马拉硫磷农药具有较好的去除效果,去除率达88%。
The adsorption of malathion 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 show that the target analytes can be removed,and the conditions as follows:sample solution volume was 20 mL,the adsorbent dosage was 0.4 g,the pH of water sample was adjusted to 5,adsorption equilibrium time was 30 min.The results showed that maize straw biochar had good removal effect on malathion in environmental water,and the removal rate was 88%.
