음이온성 Copoly(1,2,4-benzenetricarboxylate/bis[4-(3-aminophenoxy)phenyl]sulfone/3,3',4,4'-benzophenonetetracarboxylate/1,2,3,4-butanetetracerboxylate) 한외여과막의 투과특성

Performance of Anion Charged Copoly(1,2,4-benzenetricarboxylate/bis[4-(3-aminophenoxy)phenyl]sulfone/3,3',4,4'-benzophenone tetracar boxylate/1,2,3,4-butanetetracerboxylate) Ultrafiltration Membranes

In the preparation of anion charged asymmetric ultrafiltration membranes by the conventional phase inversion method, several variables could be adjusted to control membrane permeations. The anion charged materials and its original polymer have good solubility in N-methyl-2-pyrrolidone. The membranes having a hydrophilic property were less fouled the membrane prepared from the original polymer. The preparation conditions, operation conditions, and hydrophilicity of polymer have played an important role in determining the permeation properties of membranes.
