Cyclic chemiluminescence is a novel method.With a continuous success in experimental research,this method has been showing many unexpected applications,but its theoretical research is still waiting for breakthrough.Herein presented is the theoretical deduction on the cyclic chemiluminescence of luminol system sensitized by cobalt chiral complexes,based on the reaction mechanism of single electron transfer.The resulting theoretical formulas could stand the test of some literature data,which are able to figure out the theoretical meaning of the data.In addition,some of the theoretical formulas were also derived that were not very compatible with the literature speculation but could stand the test of some experimental data presently available.According to the obtained formulas,it is also able to deduce some new detection methods of cyclic chemiluminescence.This may contribute to the further researches and applications of this method.
