主 题:Poly(arylene ether ketone)-containing Carboxyl groups(PAEK-COOH) UiO-66-NH_(2)@graphene oxide Hydrophilic modification Ultra-high selectivity Strong anti-fouling
摘 要:Achieving high fouling resistance and permeability using membrane separation technology in water treatment processes remains a *** this work,a novel mixed-matrix membrane(MMM)(poly(arylene ether ketone)[PAEK]-containing carboxyl groups[PAEK-COOH]/UiO-66-NH_(2)@graphene oxide[GO])with superb fouling resistance and high permeability was prepared by the nonsolvent-induced phase separation method,by in-situ growth of UiO-66-NH_(2) on the GO layer,and by preparing hydrophilic *** the basis of the structure and performance analysis of the MMM,the maximum water flux reached 591.25 L·m^(-2)·h^(-1) for PAEK-COOH/UiO-66-NH_(2)@GO,whereas the retention rate for bovine serum albumin increased from 85.40%to 94.87%.As the loading gradually increased,the hydrophilicity of the MMMs increased,significantly enhancing their fouling *** strongest anti-fouling ability observed was 94.74%,which was 2.02 times greater than that of the pure *** the same time,the MMMs contained internal amide and hydrogen bonds during the preparation process,forming a cross-linked structure,which further enhanced the mechanical strength and chemical *** summary,the MMMs with high retention rate,strong permeability,and anti-fouling ability were successfully prepared.
