| Abstract: | The conditions of the photochemistry for the iodide ion and the chemilumi-nescence for the iodme-luminol were investigated and a novel system of chemiluminescence analysis with photochemistry couple reaction was established. A low pressure mercury lamp was used as exciting light source. The best conditions for the reactions were given. The interference of cations could be eliminated by using cationic exchange resin. This method has been applied to determinate the sulfite in food. The relative standard deviation was less than 5% and the recoveries were 90%-110%. |
