Experimental Study on S2-Removal by Hydrogen Peroxide Oxidation of Molybdenum Desorption Solution
The desorption solution of thiomolybdate-saturated resin(molybdenum desorption solution)was treated by hydrogen peroxide oxidation and sulfuric acid regulation.The effects of the type,dosage and adding method of oxidants,and the temperature and time of reaction on S2-removal from molybdenum de-sorption solution were studied.The results show that under the conditions of reaction temperature of 35 ℃,constant stirring speed of 200 r/min,hydrogen peroxide dosage of 1.0 time the theoretical amount add-ed at once,and reaction time of 20 min,the concentration of S2-in the molybdenum desorption solution could be reduced to below 0.01 g/L,and no hydrogen sulfide gas or molybdenum trisulfide slag are detec-ted in the acid regulation process.This method provides a reference for the green and efficient treatment of molybdenum desorption solution in ion exchange section.
