In this work, a simple supported liquid membrane transport strategy is applied to remove of the dichlorophenoxyacetic acid (2,4-D) from water samples as important agricultural pesticides. Here, the electrospun polyacrylonitrile (PAN) nanofiber-based sheet has been used in the SLM process as new support. The optimal SLM transport working parameters were found to be pH = 1 and NaCl solution of 2 M for feed phase, dichloromethane as solvent of liquid membrane and pH = 14 and NaCl solution of 2 M for receiving phase. The stirring speed, time and temperature of SLM and the interference effect for 2,4-D transport have been studied and optimized. We find that the thickness of nano-electrospun PAN sheet as support of the liquid membrane has important effect on decreasing the time of transport. Under the same working conditions, this nano-based SLM method shows significant enhancement for removing efficiency and rate of 2,4-D rather than PAN microfiltration flat sheet as support material.

在这项工作中，采用了一种简单的支持性液膜运输策略，以从水样中去除作为重要农业农药的二氯苯氧基乙酸（2,4-D）。在这里，电纺聚丙烯腈（PAN）纳米纤维基片材已在SLM工艺中用作新的载体。发现最佳的SLM传输工作参数是：进料相的pH = 1和2 M的NaCl溶液，液膜的溶剂是二氯甲烷，接收相的pH = 14和2 M的NaCl溶液。研究和优化了SLM的搅拌速度，时间和温度以及对2,4-D传输的干扰作用。我们发现，以纳米电纺PAN片为支撑液膜的厚度对减少运输时间具有重要影响。在相同的工作条件下
