Abstract: Achemiluminescence sensor for Mn2+combined with flow-injection system is presented in this paper. It was based on the new approach that all of the reagents involved in the chemiluminescence reaction were immobilized electrostatically on Amberlyst A-27 anion-ex-change resin. Mn2+can be sensed directly by the reaction with Luminol and IO4-, which were eluted by Na3PO4from the immobilization column prior to the chemiluminescence reaction. The linear range for Mn2+is 2. 0×10-9-1.0×10-5g/mL. The detection limit is 1.0×10-9g/mL. The column with immobilized chemiluminescence reagents in the resin can be used for 100 times. The sensor has been applied to the determination of Mn2+in water samples.
