Characteristic of peroxyoxalate-chemiluminescence intensity in the presence of Chlorpheniramine maleate and its analytical application

摘要

It has been shown that Chlorpheniramine maleate (CPM) increases chemiluminescence intensity of bis-(2,4,6-trichlorophenyl)oxalate (TCPO) with hydrogen peroxide in the presence of biphenylquinoxaline as a fluorophore. In this work, the effect of CPM on the intensity of chemiluminescence (CL) in the system of (TCPOsodium salicylatefluorophorehydrogen peroxide) was investigated. The fall and rise rates constants were also studied. A pooled-intermediate model was used for determining the kinetics parameters of CL with and without CPM. Results indicated that addition of CMP to this system increases the fall rate constant and decreases the rise rate constant. Results also specified that there is a linear relationship between CPA concentration and chemiluminescence intensity in the range 0.6621.5 μg/ml. Detection limit 0.18 μg/ml and the relative standard deviation (RSD) <7 was obtained. This work is introduced as a new method for the determination of CMP.
