The cross linking of ADC with chloromethylthiiane in the presence of alkaline gave six new chelating resins(TADC 1-TADC 6) which contain sulfur and nitrogen. The conditions of synthesis for CDC, ADC and TADC were studied. The adsorption properties of ADC resins and TADC resins for metal ions were thoroughly studied. It was found that ADC resins possessed high capacities for Hg 2+ (about 0.5 mmol/g) and TADC resins did for Hg 2+ (1.1 mmol/g) and Ag +(1.9 mmol/g). The effect of pH value on adsorption capacities of ADC resins was more remarkable than on TADC resins. The adsorption capacities of ADC resins and TADC resins were in the order Hg 2+ >Cu 2+ >Ni 2+ and Ag +>Hg 2+ >Cu 2+ and they can be reused by desorption of 15% ammonia hydroxide.
