摘　　要：本文采用以活性炭作催化剂的曝气 /紫外光体系 ,对染料活性艳红 X- 3 B的光氧化脱色进行了试验。结果表明 ,酸性条件下 ,活性炭对脱色反应具有显著催化作用。初步分析认为主要机理是活性炭吸附氧分子反应生成了 H2 O2 ,进而在紫外光作用下产生了强氧化性的· OH自由基。脱色反应为动力学零级反应。The decoloration of Reactive Brilliant Red X-3B in Aeration/UV system with Activated Carbon as catalyst was studied, and preliminary analysis about the mechanism of catalysis was done. The results showed that the main affecting factors in the system is pH, and stronger acid is the proper condition. The decoloration reaction is a zero order.
