Abstract

In this paper, a new chemiluminescence phenomenon described as the second chemiluminescence emission was observed when menadione sodium bisulfite was injected into a reaction mixture of luminol and potassium periodate, in which luminol was oxidized by excess amount of potassium periodate for about 24 h. The mechanism of the second chemiluminescence emission was proposed based a series of experiments. Moreover, our experiment discovered that the second chemiluminescence intensity was a linear function of the concentration of menadione sodium bisulfite in the range of 2 × 10−9 to 4 × 10−5 g L−1. Based on this phenomenon, a new flow-injection method for the determination of menadione sodium bisulfite has been established.
