| 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。

| Abstract: | A novel photodecomposition behavior of hemin was described.With RhB-H_2O_2 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. |
