Am inocarboxylic acid chelating resin and am inophosphonic acid chelating resin are synthesized from PS-TEPA respectively. The static adsorption characters of the resins for Cu2+ , Zn2+ and Ni2+ are studied. The adsorption cap acity of aminocarboxylic acid resin chelated Cu2+ , Zn2+ and N i2+ f or BSA- V is more than that of am inophosphonic acid chelating resin. Key words: acetylated polystyrene Mannich reaction am ino resin chelating resin adsorption ( PS)
