Mo0协同Fe3+活化过氧乙酸降解水中罗丹明B研究
Study on the degradation of rhodamine B in wastewater by activation of peracetic acid with Mo0 and Fe3+
摘要
Abstract
The advanced oxidation processes utilizing the activation of peracetic acid(PAA)to generate reactive oxygen species for the degradation of organic pollutants has been exten-sively studied in the past few years.This study verified the effectiveness of PAA activation for degrading Rhodamine B(RhB)in wastewater.The system used Fe3+and Mo0 as homo-geneous and heterogeneous catalysts,respectively,while PAA acted as an oxidant.It ex-amined the RhB removal under various conditions,optimizing several key parameters,e.g.,types of catalysts,initial pH,the dosage of Mo0,and concentrations of Fe3+and PAA.The results indicated that Mo0 synergistically combined with Fe3+could effectively degrade RhB.The optimal conditions were found to be 5.87 of initial pH,0.5 g/L of Mo0,0.1 mmol/Lof Fe3+,and 0.5 mmol/L of PAA.The presence of Cl-and NO-3 in the reaction system had little effect on the RhB removal,whereas HCO-3 and H2 PO-4 signifi-cantly inhibited the degradation process.Besides,the Mo0 showed a good stability.Quenching experiments demonstrated that both free radicals and non-radical reactive species were generated in the reaction system.关键词
