摘要

采用双氧水氧化-硫酸调酸的方式处理吸附硫代钼酸根饱和树脂的解吸液(解钼液),研究了氧化剂种类、用量和添加方式以及反应温度和时间对解钼液中S2-去除效果的影响.结果表明:在反应温度35 ℃、搅拌速度恒定(200 r/min)、双氧水用量为理论量的1.0倍并一次性添加以及反应时间20 min条件下,解钼液中S2-的浓度可降到0.01 g/L以下,调酸过程未检测到硫化氢气体和三硫化钼渣.此方法为离子交换工段解钼液的绿色、高效处理提供了一种参考.

Abstract

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.
