摘　　要：在线分光光度技术应用于Fe3^+/H2O2/H^+体系对偶氮染料活性红SBE的降解研究,并考察Fe3^+的初始浓度、pH值和H2O2初始浓度等条件对降解过程的影响。结果表明:最佳的实验条件下:Fe3^+投加量0.9681mmol/L,H2O2投加量30.88mmol/L和pH值为3.0,在250s后,活性红SBE的去除率达到87%。对产物进行分析确定主产物为邻苯二甲酸乙酯,并推测活性红SBE的降解机理。On-line spectrophotometry was applied to the degradation of reactive red SBE with Fe3^+/H2O2/H^+system.The effects of Fe3^+concentration,pH value and H2O2 concentration on the degradation of reactive red SBE were investigated.The results showed that the best experimental conditions were 0.9681mmol/L Fe3^+,30.88mmol/L H2O2 and pH3.0 with 87%color removal after 250s.The by-product was ethyl phthalate and degradation mechanism was also speculated.
