摘　　要：利用罗丹明B(RhB)-H2O2化学发光体系及流动注射技术,研究了十二烷基磺酸钠(SDS)存在下,氯化血红素在紫外光下的光解反应动力学规律,并与不加入SDS时氯化血红素光解行为进行了对比。结果表明:SDS存在与否,氯化血红素的光解行为均符合一级动力学反应方程。但是加入SDS后所形成的胶束相,减缓了氯化血红素的光解速度,提高了其光稳定性。A novel photodecomposition behavior of hemin was described. With RhB-H2O2 system a flow injection chemiluminescence method has been applied to the study of the photolytic kinetics of hemin under ultraviolet light. And the sodium dodecyl sulfonate （SDS） was added as a photostability-stabilizer. The results showed that the decomposition reaction of hemin in the presence and absence of SDS corresponded to a first-order reaction. Furthermore, the presence of SDS in the system decreased the photolytic rate of hemin by 1.8 times compared to that in the absence of SDS.
