铁碳微电解活化过硫酸盐降解布洛芬的实验研究

Degradation of Ibuprofen by Combination of Iron-Carbon Micro-Electrolysis Coupled with Persulfate Treatment

采用铁碳微电解耦合过硫酸盐处理布洛芬废水。考察了pH值、铁粉投加量、铁碳比、过硫酸盐投加量等因素对处理效果的影响,并通过正交实验确定了最优条件。结果表明:在初始pH值为3、铁碳比为1∶1、铁粉投加量为10 g/L、过硫酸钠投加量为8 mmol/L的最优条件下,布洛芬的去除率达到77.46%。

Ibuprofen was degraded using method of persulfate reinforced iron-carbon micro-electrolysis.The effects of initial pH,iron powder dosages,iron-carbon ratio,PS dosages on ibuprofen removals were investigated and the reaction conditions were optimized.The results showed that the optimum reaction conditionswereinitial pH of 3.0,iron-carbon ratio of 1∶1,iron dosage of 10 g/L,PS dosage of 8 mmol/L.Under this condition,the removal rate of ibuprofen reached 77.46%.
