摘要/Abstract

摘要： 采用催化湿式过氧化氢氧化法（CWPO）对间硝基苯磺酸钠溶液进行降解, 比较了不同的催化剂（Co/Bi, Mn/Ce, Cu/Mn/Ce, Cu(NO₃)₂, 活性炭）和氧化剂（过氧化氢和氧气）对间硝基苯磺酸钠的降解效率, 并研究了催化剂用量、初始氧分压、间硝基苯磺酸钠浓度、过氧化氢用量、反应温度对去除效率的影响. 结果表明, 以Cu(NO₃)₂为催化剂的CWPO法对间硝基苯磺酸钠具有较理想的降解效果, 反应温度、过氧化氢用量和间硝基苯磺酸钠的浓度对降解反应具有显著的影响, 氧气和催化剂的加入能提高反应效率, 此外, 升温过程也对CWPO降解间硝基苯磺酸钠有较大影响.

Abstract: Degradation of sodium mnitrobenzene sulfonate was investigated by the catalytic wet peroxide oxidation (CWPO), and the removal effectiveness of the degradation were compared under conditions of different catalysts (Co/Bi, Mn/Ce, Cu/Mn/Ce, Cu(NO₃)₂, and activated carbon) and oxidants (peroxide and oxygen). Meanwhile, the effects of the reaction conditions, including reaction temperature, amounts of peroxide and catalyst, oxygen partial pressure and the initial concentration on the removal efficiencies were also discussed. The results show that sodium mnitrobenzene sulfonate was more efficiently decomposed by CWPO with Cu(NO₃)₂ as catalyst; the reaction temperature, am ounts of peroxide and sodium mnitrobenzene sulfonate have significant influence on the degradation reaction. Besides, the addition of oxygen and catalyst can enhancethe degradation efficiency. Otherwise, the temperatureincreasing process has important influence on the degradation of sodium mnitrobenzene sulfonate through CWPO.
