摘　　要：研究了废钒催化剂中的钒、钾在硫酸亚铁酸溶液中的溶解行为,考察了搅拌时间、水浴温度、搅拌速度、液固体积质量比、Fe^2+浓度及废钒催化剂粒度对钒、钾浸出的影响。结果表明:在搅拌时间5min、水浴温度20~30℃、搅拌速度200r/min、液固体积质量比6∶1、FeSO4·7H2O质量浓度0.028g/mL、废钒催化剂中粒度≤200目的颗粒占比为91%条件下,钒、钾浸出率分别为88%和70%,浸出效果较好。The dissolution of vanadium and potassium from waste vanadium catalyst using FeSO4-H2SO4 solution was studied.The effects of stirring time,temperature,stirring speed,liquid-to-solid mass ratio,Fe^2+concentration and waste vanadium catalyst particle size on leaching of vanadium and potassium were examined.The results show that the optimum conditions are as follows:stirring time of 5 min,water bath temperature of 20~30℃,stirring speed of 200 r/min,liquid-to-solid mass ratio of 6∶1,FeSO 4·7H 2 O mass concentration of 0.028 g/mL,the proportion of waste vanadium catalyst particle with porticlal size-200 mesh of 91%.
