Experimental Study on Oxidative Degradation of Butyl Xanthate Wastewater by Fenton Reagent
Butyl xanthoxanthate is one of the main collectors of metal sulfide ores because of its strong collecting ability and better selective performance in ore flotation.Therefore,the degradation treatment of wastewater containing butyl xanthate has been widely concerned by relevant workers.In this paper,the effect of different degradation conditions on the degradation rate of butyl xanthate simulated wastewater was studied.The results showed that the number of hydroxyl radicals produced by either ferrous ion alone or hydrogen peroxide alone was very small,and the butyl xanthate could not be oxidized and degraded.The oxidative degradation of butyl xanthoxanthate was better by ferrous+hydrogen peroxide+light system.With the increase of initial concentration of butyl xanthate,the oxidative degradation efficiency of butyl xanthate decreased.In the range of 2 mg～8 mg ferrous chloride,the degradation rate of butyl xanthate increased with the increase of ferrous chloride dosage.In the range of 20 μL～60 μL hydrogen peroxide,the degradation rate of butyl xanthoxanthate increased with the increase of hydrogen peroxide dosage.With the increase of pH value of solution,the oxidative degradation rate of butyl xanthate with initial concentration of 20 mg/L decreased.
