【Abstract】 The solid surface chemiluminescence analysis (SSCL) with identical chemilumi-nescence area using the anti-permeate barrier was developed,the chemiluminescence characteristics on a solid surface,the luminescence homogeneity and reproducibility,the choice and purification of solid carrier were investigated. The linear ranges and detection limits of thirteen ions and biological activity materials were determined. The researches show that SSCL has all the advantages of solid surface fluorescence analysis (SSF) and solid surface room temperature phosphorescence analysis (SSRTP),and is one of the most attractive techniques to overcome the problems suffered in SSF and SSRTP. Since no excitation source is needed, SSCL is prevented from interference of scattering, allowing the use of a wide range of solid substrate. Moreover, the instrumentation is simple, it can be used to analyze small amount of sample.更多还原
