Preparation of poly(methacrylic acid) grafted on SiO2-NH2/PSF composite membranes for amlodipine removal

Abstract

Firstly, the SiO2 microspheres were prepared by Stӧber method, and then modified by 3-Aminopropyltrimethoxysilane (KH-540) to introduce –NH2 onto the microspheres. Then, SiO2-NH2 microspheres were ...
