【摘要】 简述钨冶炼工艺流程中离子交换法的发展历程、离子交换的动力学理论;并对离子交换过程中影响交换容量的各因素进行分析。结果表明:D₂₉₀交换树脂在WO₃浓度14～24mg/ml时吸附效果最佳,D₂₉₀交换树脂线速度为2.30ml/min时吸附量较大,Cl^-的存在将使交换容量大幅度下降、酸度条件当pH=10.5时,树脂的交换容量最大。更多还原

【Abstract】 The development of ion-exchange method in tungsten smelting process and kinetic theory of ion-exchange are described. The various factors which affect the exchange capacity in the process of ion exchange are analyzed.The results show that the effect of adsorption is the best when the concentration of WO₃ is 14-24mg/ml for resin D₂₉₀,the adsorption is the largest when line velocity is 2.30 ml/min for resin D₂₉₀,the existence of Cl^- made exchange capacity decrease sharply,the exchange capacity is the largest when pH=10.5 for resin D₂₉₀.更多还原
