This study focused on the investigation of emulsion stability, membrane breakage, and emulsion swelling of an emulsion liquid membrane for acetaminophen (ACTP) removal. Stability of the emulsion as well as its effectiveness in removing ACTP from aqueous solution were considered for the optimization of parameters. Parameters involved are carrier and surfactant concentration, emulsification time, as well as volume ratio of membrane to internal phase. The effects of membrane breakage and emulsion diameter on the removal capacity of ACTP were also studied. Results showed that the optimal conditions to produce a very stable emulsion and to achieve maximum ACTP removal efficiency were found to be 4 wt % of trioctylamine (TOA) and Span 80, W/O volume ratio of 3, and 10 min of emulsification time. The prepared emulsion was found to effectively remove 85% of ACTP at minimal membrane breakage of 0.19%.

乳状液膜从水溶液中去除对乙酰氨基酚的研究：乳状液稳定性研究

这项研究的重点是研究乳状液膜对乙酰氨基酚（ACTP）去除的乳状液稳定性，膜破损和乳状液溶胀。为了优化参数，考虑了乳液的稳定性以及从水溶液中去除ACTP的有效性。涉及的参数是载体和表面活性剂的浓度，乳化时间以及膜与内相的体积比。还研究了膜破裂和乳液直径对ACTP去除能力的影响。结果表明，产生非常稳定的乳液并达到最大ACTP去除效率的最佳条件为三辛胺（TOA）和Span 80的重量百分比为4％，W / O体积比为3，乳化时间为10分钟。
