摘　　要：紫外光(UV)及紫外光-过氧化氢(H2 O2)对水中微量甲苯均有较好的降解作用,UV-H2 O2 降解效果更佳。研究了UV-H2O2降解中,H2O2用量对降解速率的影响。初步探讨了两种光降解技术的机理。The degradations of toluene from water in micro-pollution level by UV and UV-H_2O_2 were both effective. But the result of the latter was better. Each degradation reaction could be described by the first-order kinetic equation. And the effect of H_2O_2 addition on the UV-H_2O_2 degradation was studied. The mechanism for degradation of toluene by each technology was proposed.
