Degradation of aniline by dielectric barrier discharge combined with sodium bismuthate
摘要
Abstract
In order to make the best use of oxidants and UV irradiation in dielectric barrier discharge (DBD), catalyst sodium bismuthate was added into a rod-plate DBD reactor.The spectral characteristics of DBD and the effects of pH value, aniline initial concentration, and catalyst dosage on aniline degradation rate were investigated.The synergistic catalytic mechanism of aniline removal was discussed.The results show that the radiation of UV and visible light was produced in the discharge process, and the highest intensity spectral in the range of 300-450 nm is N2 second positive band line.The degradation efficiency of 100 mg/L aniline was improved after sodium bismuthate being added, and total organic carbon (TOC) removal was improved 14.11％ with 0.2 g/L catalyst addition.Under alkaline condition, the degradation rates of aniline and TOC were better than that of acid and neutral conditions.The XRD test results showed that the peak position of the sodium aluminate before and after the reaction did not change significantly.关键词
