摘要
Abstract
In this study,cellulose acetate porous membranes with an adjustable structure and a high water flux were pre-pared by using cellulose acetate as a raw material,acetone as a solvent,and water as a non-solvent.Carboxyl groups were introduced for selective separation of protein through the oxidation of tetramethylpyridine oxide/sodium bromide/so-dium hypochlorite.With a porosity of 92.5％and a water flux of 1 655.7 L/(m2·h),the cellulose acetate porous mem-branes exhibited optimal comprehensive performance at a cellulose acetate concentration of 10 wt％,a coagulation bath temperature of 10 ℃,and a non-solvent water content of 30 wt％.After oxidation,the cellulose acetate porous mem-brane obtained an adsorption rate of 2 806.1 mg/g for lysozyme at pH 6.关键词
