Six types of consumed chemiluminescence sensors for ascorbic acid, cyanide, Mn^2^+, Co^2^+, and H~2O~2 have been developed. It was based on the new approach that all of the reagents involved in the chemiluminescence reactions were immobilized electrostatically on Amberlyst A-27 or D151 ion-exchange resin. The analytes of interest can be sensed directly by the reaction with the chemiluminescence reagents, which were eluted by Na~3PO~4 or NaCl from the immobilization column prior to the chemiluminescence reaction. Not only these sensors have a wide linear range high sensitivity and simplicity for instrumentation, but also the immobilization methods of the chemiluminescence reagents are simple. They have been applied successfully to the determinations of analytes in various samples.
