| 摘 要： | 以偶氮染料酸性橙AO7为目标污染物,研究了单独的热活化及零价铁（ZVI）活化S2O28-（PS）降解AO7过程温度、PS浓度及ZVI投加量对AO7降解率的影响,并将2种活化方式进行了对比,最终将其联合以期获得最好的降解效果.结果表明,热活化体系对AO7的降解符合一级动力学,其反应速率随温度（室温～90℃）升高而增加,随...

| Abstract: | Effects of temperatures,PS concentrations and ZVI dosages on AO7 decomposition were investigated in sole heat and ZVI activating systems.The degradation results of two systems were compared for selecting a better activating way for AO7 degradation and finally the two activating ways were combined for getting the optimal AO7 degradation efficiency.The degradation of AO7 by Heat/PS systems followed pseudo first-order kinetics.The reaction rates increased with increasing reaction temperatures(elevated from roo... |
