摘　　要：研究了在高压汞灯照射下N,N′-二正辛基-3,3′-二硫代二丙酰胺的光降解过程,经由高效液相色谱法测定其残留含量。通过对比实验研究了不同初始浓度和光照强度对N,N′-二正辛基-3,3′-二硫代二丙酰胺光降解的影响。结果表明N,N′-二正辛基-3,3′-二硫代二丙酰胺在低浓度和高光强度时光降解速率更大,其降解过程符合动力学一级反应规律。This paper reported and the photochemical degradation progress of N,N＇-di-n-octyl-3,3＇-dithiodipropionamide .（OPD） under high-pressure mercury lamp, RP-HPLC method was used to determine the residual concentration of OPD which was exposed to the high-pressure mercury lamp. The result showed that OPD was degradated pronouncedly under high-pressure mercury lamp. The degradation followed a first-order kinetics, and was more rapid in a lower concentration of OPD and a higher light intensity.
