Two calixarene-linked chitosans were synthesized by the reaction of chitosan with 1,3- diglycidyl calix\arene. The adsorption properties of these two cross-linked chitosan towards Co 2+ , Cu 2+ , Zn 2+ , Ni 2+ and Na + , K + , Cs + were studied. N-crosslinked chitosan （N-CC） exhibits a higher adsorption ability towards Ni 2+ ,O-crosslinked chitosan （O-CC） has a higher adsorption ability towards Cu 2+ , and O-CC has a higher adsorption ability towards Co 2+ ,Cu 2+ ,Zn 2+ than that of N-CC. The calixarene-linked chitosan exhibited much higher adsorption ability towards Na + , K + , Cs + than its mother chitosan did. The adsorption properties of linked chitosan towards Co 2+ , Cu 2+ , Zn 2+ , Ni 2+ varied with the linked type. 壳聚糖 杯芳烃 离子吸附 chitosan calixarene ion adsorption O636.1 国家自然科学基金资助项目（203231615） 2004-04-01 2021-04-01 4
