摘　　要：文章详述了磷钼酸铵对铷离子的离子交换特性,考察了不同时间、温度、振荡频率以及铷离子浓度对交换能力的影响。试验结果表明,在最佳工艺条件下磷钼酸铵对铷离子的离子交换量最高可达1.56 mmol/g。此外,K+和Cs+的存在对离子交换能力有一定的影响。The ion-exchange characteristics of the Ammonium molybdophosphate（AMoP）for Rb ＋ had been detailed studied.The difference of time,temperature,oscillation frequency and Rb ＋ concentration on ion-exchange capacity were investigated.The experimental results indicated that ion-exchange capacity of the AMoP could reach up to 1.56 mmol / g wastewater on the optimum operating conditions.Moreover,the results showed that the existing of K＋and Cs＋both affected the ion-exchange capacity.
