Facilitated transport of Orange 3R was performed by means of emulsion liquid membrane (ELM) technique containing double extractants of Aliquat 336 and D2EHPA as extractant and synergist extractant, respectively. Cooking palm oil, sorbitan monooleate (Span 80), and sodium hydroxide were used as diluent, surfactant and stripping agent, respectively. Several parameters influencing the extraction of Orange 3R via ELM, namely effect of extraction time, agitator speed, Span 80 concentration and treatment ratio, were experimentally investigated and optimized using response surface methodology (RSM). Results demonstrated that about 91% of Orange 3R was successfully extracted under optimum conditions of 12 minutes of extraction time, 413 rpm of agitator speed, 3.2% (w/v) of sorbitan monooleate, and 1:9.8 of treatment ratio. Additionally, the aforementioned optimum conditions were found to be more suitable to treat low concentration of Orange 3R (less than 100 ppm) from simulated textile wastewater. The findings reveal that reactive Orange 3R dye is able to be selectively extracted using double extractants via sustainable ELM process as well as providing high potential application in the dye removal from industrial textile wastewater.

乳液液膜系统协同Aliquat 336/D2EHPA提取活性染料

Orange 3R 的易化转运是通过乳化液膜 (ELM) 技术进行的，其中含有 Aliquat 336 和 D2EHPA 的双重提取剂，分别作为提取剂和协同提取剂。烹调棕榈油、脱水山梨糖醇单油酸酯（Span 80）和氢氧化钠分别用作稀释剂、表面活性剂和汽提剂。影响通过 ELM 提取 Orange 3R 的几个参数，即提取时间、搅拌器速度、Span 80 浓度和处理比率的影响，使用响应面方法 (RSM) 进行了实验研究和优化。结果表明，在提取时间 12 分钟、搅拌器转速 413 rpm、脱水山梨糖醇单油酸酯 3.2% (w/v) 和处理比 1:9.8 的最佳条件下，约 91% 的 Orange 3R 被成功提取。此外，发现上述最佳条件更适合处理模拟纺织废水中的低浓度橙 3R（小于 100 ppm）。研究结果表明，活性橙 3R 染料能够通过可持续的 ELM 工艺使用双萃取剂进行选择性萃取，并在工业纺织废水中的染料去除方面具有很高的应用潜力。
