Abstract: The preparation and properties of adsorbing to Cu (Ⅱ) and Ni(Ⅱ) of chitosan modified by ethylene glycol bisglycidal ether were studied. The effects of pH, time and temperature on the adsorption were investigated. The results show that the modified chitosan is easy to be regenerated and uneasy to run off in acidic solution and it has an adsorption selectivity for Cu(Ⅱ) when Cu(Ⅱ) and Ni(Ⅱ) are present simultaneously in the solution.

Key words: natural macromolecule, chitosan, adsorption, Cu (Ⅱ), preparation
