VUV/UV耦合原位E-Peroxone去除水中壬基酚研究
Removal of nonylphenol from aqueous solution by VUV/UV coupled in-situ E-Peroxone process
摘要
Abstract
A coupled photoelectric advanced oxidation technology based on the in-situ peroxone system(VUV/UV-EOP-Peroxone)was constructed,with mesh titanium-based antimony and nickel doped tin oxide(Ti/SnO2-Sb-Ni)electrode as the anode,filtered activated carbon fiber felt as the cathode,and dual-wavelength ultraviolet lamps(VUV/UV)as the light source.Nonylphenol(NP)was selected as the target pollutant,and the effects of current intensity,system temperature,initial pH and substrate concentration on NP degradation were investigated respectively.The results showed that under the conditions of applied current of 400 mA,reaction temperature of 25℃,initial pH of 7,0.05 mol/L Na2SO4 electrolyte and initial NP concentration of 1 mg/L,an NP removal rate of 91.5%was achieved after 20 minutes of reaction.Slight impacts on the degradation performance were caused by pH.The removal rate of NP was accelerated to varying degrees when the current and system temperature were increased and the substrate concentration was reduced.Radical quenching tests proved that hydroxyl radical(·OH)was identified as the dominant radical in the reaction system,and its contribution rate to NP degradation was determined to be 85.5%.关键词
