摘要
就大孔膦酸树脂(简称PAR)对铽(Ⅲ)的吸附性能进行了研究.实验选在pH为5.6的HAc-NaAc缓冲体系中进行.在实验条件下,树脂吸附铽离子的吸附速率随铽离子质量浓度的增大而增大,随温度的升高而增大,随振荡频率的增大而增大,随树脂粒径的减小而增大.
The absorptive behavior of macroporous phosphonic acid resin (PAR) for terbium(Ⅲ) was investigated systematically. The experiment was carried out at pH 5.6 in HAc-NaAc medium. Under the experimential conditions, the absorption rate of PAR for Tb(Ⅲ) increased with the rise of the concentration, temparature, oscillation frequency and granularity.
