摘要： 化学和生物发光是由化学反应产生的一种光辐射,不需要任何光源。又由于它们具有高灵敏度、宽线性范围和相对比较便宜的仪器等优点,因而在化学和生物传感器领域引起了广泛的兴趣。已用于H2O2、乳酸和胆固醇等多种生物活性物质的测定,但未见有金属离子传感器的报道。

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.

Key words: Chemical sensor, Mn2+, Solid-state format, Chemiluminescence
