摘　　要：在高压汞灯下,研究了几种阴离子对戊唑醇光解的影响。结果表明:硝酸盐和亚硝酸盐对戊唑醇的降解均具有明显的光猝灭作用,且随着添加浓度的增加,这种猝灭效应逐渐增强,亚硝酸盐的猝灭作用强于硝酸盐;3种卤素离子对戊唑醇都具有光猝灭作用,但是猝灭效应的强弱不同,其中碘离子>溴离子>氯离子。Seveaal negative ions could change the rate of photochemical degradation of tebuconazole, The results indicated： NO3^- and NO2^- had sicnificantly photoquenching effect on photochemical degradation of tebuconazole in aqueous solution, with increasing of concentration, the photoquenching effect on photochemical degradation of tebuconazole in aqueous solution got stronger. The photochemical degradation of tebuconazole in aqueous solution was inhibited significantly by Cl^-, Br and I , and the photoquenching effect of I^- was followed by Br^- and then by Cl^-.
