碱性离子交换制取钼酸铵溶液研究

Research of preparation of ammonium molybdate solution by ion-exchange process in alkaline environment

研究了高杂钼酸钠溶液在某强碱性CO_3^(2-)型树脂上的吸附解吸情况,考察了溶液中的P、Si、As、V等杂质在离子交换中的行为,根据实验得出Mo吸附解吸的最佳条件。结果表明,树脂对P、Si、As的去除效果良好,除杂率在96%以上。

In this paper,the adsorption and desorption of sodium molybdate solution onto one strongly alkaline CO_3^（2-） style resin using ion-exchange process was researched,and the behaviors of P,Si,As,and V were investigated. The Mo optimum adsorption and desorption condition was got based on experiment.The behaviors of impurity P, Si,As in ion-exchange process were studied,the removal rates are all above 96%.
