过硫酸盐降解橙黄 II 性能研究

摘要

With the azo dye wastewater as treatment purpose the oxide degradation of Orange II by persul-fate activated by ferrous has been studied.The effects of degradation time,persulfate concentration,initia-tor FeSO4 concentration,pH value on Orange II degradation has been investigated,respectively.The re-sults show that persulfate activated by ferrous can oxidate and degrade Orange II effectively.The degrada-tion efficiency of Orange II could get 98.8% in 139 min with persulfate concentration 5 mmol /L,initiator concentration 10 mmol /L,and pH =3.%以偶氮染料废水为处理目标，采用 Fe2＋活化过硫酸盐氧化降解橙黄 II。考察降解时间、过硫酸盐浓度、引发剂 FeSO4浓度、pH 值等因素对过硫酸盐降解橙黄 II 的影响。研究发现，Fe2＋活化过硫酸盐能有效氧化降解橙黄II 废水，过硫酸盐最终浓度为5 mmol／L，引发剂浓度10 mmol／L，pH ＝3时，139 min 橙黄 II 降解率可达到98．8％。
