Nowadays new membrane techonologies have a crucial role in the separation processes. However, membrane fouling is the main important limiting aspect for future propagation in different and competition with the other separation processes industries, especially in the case of liquid membrane.
In this study, the separation of bentazon was studied in an aqueous solution using a supported liquid membrane (SLM) while varying different operational parameters based on the experimental design method of the response surface. D2EHPA/M2EHPA was used as a mobile carrier, microporous cellulose acetate film was used as a solid support for the liquid membrane, and the strip phase was hydrochloric acid. The effects of different parameters such as feed concentration, carrier concentration, feed pH, and strip phase pH on the separation performance and flux of bentazon were studied. The optimum values at which the maximum flux were achieved were 1.06 for feed pH, 20 vol.% for D2EHPA/M2EHPA concentration in the membrane phase, 1.28 molar for strip concentration, and 28 ppm for feed concentration. Under these optimum conditions, the removal of Bentazon from aqueous solution achieved to 50.84%.
