| Abstract: | A blending chelate filter membrane with high chelate capacity for Ag+ has been prepared by blending of phosphoramidic acid resin and polysulfone. The major parameters influencing structure of the chelate filter membranes such as the blending ratio, phosphoramidic acid resin grain size and temperature of casting solution have been studied. The relationship among the chelate amount of Ag+, pH value, Ag+ concentration and phosphoramidic acid resin grain diameter were examined. The chelate filter membrane had a capacity of1438μg/cm2 for Ag+ under appropriate conditions.Sorption isotherm of Ag + could be expressed with the Freundlich sorption model. The dynamic chelate experiments proved that the sorption and desorption of membranes could be realized simultaneously for Ag+. |
