在详细研究HCI体系中Zn(Ⅱ)、Ca(Ⅱ)、Mg(Ⅱ)离子在P_(507)萃淋树脂上淋洗行为的基础上,提出RE(Ⅲ)离子与Zn(Ⅱ)、Ca(Ⅱ)、Mg(Ⅱ)离子的分离条件,通过红外光谱法,饱和容量法等方法研究了Zn(Ⅱ)离子与P_(507)萃淋树脂的作用机理。
Based on the detailed study on the leaching behavior of Zn (Ⅱ), Ca (Ⅱ) and Mg (Ⅱ) ions on P 507 extraction resin in HCI system, the effects of RE (Ⅲ) (Ⅱ) and Mg (Ⅱ) ions, the mechanism of Zn (Ⅱ) ion and P_ (507) extraction resin was studied by means of infrared spectroscopy and saturation capacity method.
