多胺型聚苯乙烯树脂的合成及对Cu2+的吸附性能
Synthesis of polyamine-type polystyrene resin and its adsorption property for Cu2+
摘要
Abstract
A polyamine-type polystyrene resin with tetraethylenepentamine functional group was synthesized from polystyrene resin through chloroacetylation followed by the amination of tetraethylenepentamine. Effects of reaction solvent,mole ratio of raw materials,time and temperature were discussed. The adsorption property of the polyamine-type polystyrene resin for Cu2+ was also studied. The results show that the synthetic reactions can take place smoothly in THF at room temperature and the complete exchange capacity of the synthesized resin is 7.45 mmol/g. The adsorption processes of Cu2+ can be described by pseudo-second order kinetic equation. The main control step of resin adsorption for Cu2+is governed by liquid film diffusion. The adsorption of Cu2+ belongs to the Langmuir adsorption model and was valid for single-layer adsorption. The saturated adsorption capacity of the synthesized resin toward Cu2+ is 46.15mg/mL. The Cu2+ can be removed selectively from the mixed solution of Cu2+ and Ni2+ by the synthesized resin adsorption.关键词
