POLYAMIDE-BASED WATER-TREATMENT SEPARATION MEMBRANE HAVING EXCELLENT SALT REMOVAL RATE AND PERMEATION FLUX CHARACTERISTICS AND METHOD FOR MANUFACTURING SAME

摘要

The present disclosure provides a method of manufacturing a water-treatment separation membrane having improved salt rejection rate and permeable flux properties, the method including: forming an aqueous solution layer containing an amine compound on a porous support; forming a polyamide active layer by bringing an organic solution containing an acyl halide compound and a first organic solvent into contact with the aqueous solution layer; and coating a second organic solvent having a degree of volatility lower than that of the first organic solvent on the polyamide active layer, and a water-treatment separation membrane manufactured by the manufacturing method.
