چکیده	A novel heterogeneous anion exchange membrane containing a 10 non-ionic surfactant as an additive was made via dry and wet phase inversion. The effects of the drying time at different additive ratios on properties of membranes were investigated. The selectivity and the fixed ion concentration were increased by increasing the drying time, while conductivity, water uptake, and the ion exchange 15 capacity were lower. Incorporation of an appropriate amount of additive had a positive effect on the membrane properties. The most selective membrane with remarkable nitrate/ chloride selectivity of 3.1 was obtained at an ‘‘additive/ total solid’’ ratio of 0.03 and 24 h drying time.
