Abstract

ABSTRACT A flow-injection chemiluminescence (CL) analysis for the determination of analgin is presented. It is based on the CL reaction of analgin with Ce (IV) in sulphuric acid sensitized by the fluorescent dye Rhodamine 6G. The proposed procedure has a linear range of 0.05-10ug/ml, with a relative standard deviation (RSD) of 2.1% at 1.0ug/ml. The detection limit (3σ) is 0.02ug/ml. The method has been successfully applied to the determination of analgin in tablets.
