The Study on Adsorption Properties for Pd(II) of a Novel Chelating Resin Polystyrene-Supported Glucosamine

Rongjun Qu

Abstract

A novel chelating resin,polystyrene-supported glucosamine(PS-GA),was prepared and its static adsorption properties for Pd(II) such as capacity,dynamics and isotherm adsorption were studied,as well as various factors affecting the adsorption.The results indicated that: This resin had higher adsorption capacity for Pd(II).The adsorption dynamics indicated that adsorption was controlled by the liquid film diffusion.Value of adsorption activation energy calculated was 59.76 kJ/mol.The adsorption isotherms approximately fitted Freundlich equation within the range of experimental concentration.The suitable adsorption conditions were higher temperature.In addition,they had also high adsorption capacity after being regenerated by 2% thiourea in 0.1 mol/L HNO3.
