HIGH FLUX WATER-TREATMENT MEMBRANE WITH HIGH CHLORINE RESISTANCE

摘要

The present invention relates to a water treatment membrane that is obtained by forming a polyamide active layer on a multi-porous support body, wherein a ratio of a maximum value to a minimum value for a ratio of a peak height of a C=O double bond (-COOH) of a carboxyl group to a peak height of a C=O double bond (-CONH-) that is bonded with an amide group is 1.2 to 4, and the peak height values are measured using a Fourier transform infrared spectroscope after the polyamide active layer is treated with acid.
