基于原子转移自由基聚合制备新型螯合树脂及其吸附性能
Preparation and Adsorption Properties of New Chelating Resin Based on Chloromethylated Polystyrene Beads via Surface-initiated Atom Transfer Radical Polymerization
摘要
Abstract
A new chelating resin was prepared by grafting poly ( glycidyl methacrylate) ( PGMA) onto the chloromethylated polystyrene beads via surface-initialed atom transfer radical polymerization ( SI-ATRP) , and followed by the reaction of epoxy groups in the grafted PGMA with iminodiaeetie acid (IDA). The structure of chelating resin was characterized using Fourier transform infrared spectroscopy, elemental analysis, surface area and porosity analyzer. An increase in the polymerization time leads to the increases in GMA grafting yield, IDA binding amount and adsorption capacities of Ni( Ⅱ ) , Cu( D ) and Pb( Ⅱ ). When the polymerization time was 18 h, the maximum sorption capacities of Ni( Ⅱ ), Cu ( Ⅱ ) and Pb( Ⅱ ) were 1. 29, 1.19 and 0. 83 mmol/g, respectively, which were higher than those on the same type of the reported absorbent. The results indicated ATRP is a feasible method to prepare chelating resin with higher and controlled adsorption capacity.关键词
