The goal of this work is form the MIP core-shell beads with size from 100 to 250 micrometers to separate heavy metal ions with selectivity from wastewater for industry application. The first, core particles are made by suspension polymerization of poly(styrene-divinylbenzene). After that, shell layer containing metal is formed by precipitation polymerization. The various different conditions about ratio of crosslinker and monomer, concentration of solvent, and concentration of initiator in the second step are surveyed to choose the best one. The core-shell polymer beads after that are washed with acid to remove metal and obtain MIP. The final particles are packed into the column for chromatography retention analysis to determine how much concentration of metal ions can be separated. To distinguish the difference of core, core-shell and MIP particles use FTIR, SEM and TEM. AAS are used to determine concentration of metal ions. These other properties are determined by, TGA, XPS… |
