Preparation and antibacterial property of polyethersulfone hybrid ultrafiltration membrane containing GO immobilized by lysozyme
摘要
Abstract
Graphene-oxide-(GO)-provides-an-ideal-substrate-for-lysozyme-immobilization-due-to-a-large-specific-surface-area-and-abundant-functional-groups.-The-lysozyme-immobilization-on-the-GO-sheets-could-take-place-readily-by-electrostatic-interaction-of-GO-lysozyme-(GO-Ly).-The-immobilized-lysozyme-of-GO-used-as-the-addictive-was-blended-with-polyethersulfone-(PES)-to-prepare-hybrid-ultrafiltration-membrane-via-phase-inversion.-The-effect-of-GO-Ly-con-tent-on-the-morphology,hydrophilicity,separation,mechanical-and-antibacterial-properties-of-hybrid-membranes-was-investigated.-The-results-showed-that-the-surface-hydrophilicity-and-wa-ter-flux-were-significantly-improved-with-the-increase-of-GO-Ly-content.-Meanwhile,the-me-chanical-strength-of-hybrid-membrane-was-also-increased.-Especially-when-GO-Ly-content-was-1.5-%,the-water-flux-reached-up-to-318-L/(m2⋅h).-The-rejection-of-polyvinyl-alcohol-(PVA-30-000~70-000)-was-99-%-and-the-antibacterial-rate-of-the-hybrid-membrane-against-E.-coli-could-achieve-68%.关键词
