Abstract Diazinon is one of the most commonly used organophosphorus pesticides in agricultural activities, and its access to groundwater and surface waters damages the animal and plant environments. This study aimed to evaluate the applicability of the adsorption process for the removal of organophosphorus diazinon pesticide from water using multi-wall carbon nanotubes. Specifications of multi-walled carbon nanotubes were determined using FTIR, SEM, TEM and BET technologies. The effects of different parameters of pH (4 and 7), contact time (1–15 min), pesticide concentration (0.3, 0.5 and 1 mg/L) and multi-walled carbon nanotubes' dose (0.1 and 0.3 g/L) were evaluated on the process of removing diazinon by multi-walled carbon nanotubes. Based on the experimental data obtained in this study, maximum removal of diazinon (100%) from water by multi-wall carbon nanotubes are the initial concentration of diazinon (0.3 mg/L), 0.1 g/L concentration of nano-adsorbent at both pH of 4 and 7 at the contact time of 15 min. The results of the study showed that multi-wall carbon nanotubes can be used as effective and high efficient for complete removal of diazinon pesticides from aqueous solutions.

使用多壁碳纳米管高效去除水中的二嗪农农药

摘要 二嗪农是农业活动中最常用的有机磷农药之一，其进入地下水和地表水会破坏动植物环境。本研究旨在评估吸附工艺在使用多壁碳纳米管去除水中有机磷二嗪农农药的适用性。使用 FTIR、SEM、TEM 和 BET 技术确定多壁碳纳米管的规格。pH值（4和7）、接触时间（1-15分钟）、农药浓度（0.3、0.5和1 mg/L）和多壁碳纳米管剂量（0.1和0.3 g/L）等不同参数的影响对多壁碳纳米管去除二嗪农的过程进行了评估。根据本研究获得的实验数据，多壁碳纳米管从水中最大去除二嗪农 (100%) 是二嗪农的初始浓度 (0.3 mg/L)，在接触时间为 4 和 7 的纳米吸附剂浓度为 0.1 g/L 15 分钟 研究结果表明，多壁碳纳米管可以有效且高效地从水溶液中完全去除二嗪农农药。
