Study on UV/O3 of Methyl Violet Wastewater
2012
Ultraviolet ozone process was used to eliminate Methyl Violet, the effects of the type of research process, the initial solution pH, dye concentration and free radical quenching agent N-butanol on its degradation rate were studied. The experimental results showed that: comparing to UV, O3, UV/O3 three types of technology, UV and O3 technology had significant synergies, the degradation rate of Methyl Violet solution achieve 99.58% at 50min for the initial concentration of 100mg/L. increasing pH value resulted in increasing degradation rate, the degradation rate achieved 99. 8% at 50min under alkaline conditions. The remove rate decreased with increasing initial concentrations. Quenchers of free radicals inhibited the generation of hydroxyl radical and induced decreasing degradation rate. The degradation reaction of Methyl Violet by UV/O3 followed first-order law.
