In this study, an acetochlor belonging to the herbicide group was transported using a synthesized polymer inclusion membrane (PIM). Tricapryl-methylammonium chloride (Aliquat 366) and cellulose triacetate (CTA) were used as carrier and support material, respectively, in the membrane structure. The acetochlor samples taken during the transport from the donor phase containing 0.1 M HCl to the acceptor phase containing pure water were determined by Liquid Chromatography Mass Spectrometry (LC-MS/MS). The permeability coefficient (P), rate constant (k), and material flow rate (J) values were calculated at the end of the transportation processes. The recovery factor (%) was determined to be 91.2 % at the end of 240 min of transportation time. The effects of relative amounts of the target analyte, carrier, and acid type on the donor phase were determined, as well as those of the acceptor phase pH and stirring effect. The results achieved in this study suggest that a stable and environmentally sustainable polymer inclusion membrane system might be used to effectively transport acetochlor.

高分子膜系统分离乙草胺

在这项研究中，使用合成聚合物包合膜（PIM）运输属于除草剂组的乙草胺。在膜结构中，三辛基甲基氯化铵（Aliquat 366）和三乙酸纤维素（CTA）分别用作载体和支撑材料。通过液相色谱质谱法 (LC-MS/MS) 测定从含有 0.1 M HCl 的供体相转移到含有纯水的受体相期间采集的乙草胺样品。在运输过程结束时计算渗透系数（P）、速率常数（k）和材料流速（J）值。240 分钟运输时间结束时，恢复系数 (%) 确定为 91.2%。确定了目标分析物、载体和酸类型的相对量对供体相的影响，以及受体相 pH 值和搅拌效果的影响。本研究取得的结果表明，稳定且环境可持续的聚合物包合膜系统可用于有效运输乙草胺。
