The influence of several formulation and operating conditions on hexavalent chromium extraction by green emulsified liquid membranes (GELMs) was studied. An excellent removal efficiency was achieved under optimized conditions. The optimum GELM formulation in terms of stability was obtained with tri‐n‐octylphosphine oxide (TOPO) as extractant, polyglycerol polyricinoleate (PGPR) and polyoxyethylene sorbitan monooleate (Tween 80) as stabilizers in sunflower oil. Optimum GELMs showed a monomodal distribution of sizes around 1.29 µm. Results confimed that the use of a vegetable solvent and PGPR for GELM formulation is a promising alternative to petroleum organic solvents.

用于六价铬萃取的绿色乳化液膜：配方和工艺优化
研究了几种配方和操作条件对绿色乳化液膜（GELM）萃取六价铬的影响。在优化的条件下获得了出色的去除效率。用三-获得在稳定性方面的最佳GELM制剂Ñ -octylphosphine氧化膦（TOPO）作为萃取剂，聚甘油聚蓖麻油（PGPR），聚氧乙烯山梨醇单油酸酯（吐温80），如向日葵油稳定剂。最佳GELM显示出单峰分布，尺寸约为1.29 µm。结果证实，在GELM配方中使用植物溶剂和PGPR可以替代石油有机溶剂。
