改进的P507在H2SO4体系中对锆铪的静态吸附实验
Captive Adsorption of Zirconium and Hafnium in H2SO4 with Improved P507
【摘要】 对P507萃淋树脂合成条件进行了改进,并用此合成的P507树脂在H2SO4体系中进行锆铪吸附分离性能的研究。研究了在不同温度与不同酸度下P507树脂对锆铪吸附性能,并求出了分离系数;研究了最佳吸附平衡时间,Hf的不同百分含量时的分离系数以及锆铪洗脱条件。
【Abstract】 The improvement of the synthesis of P507 solvent impregnated resins,and the performance of adsorption and separation of Zr(Ⅵ) and Hf(Ⅵ) in H2SO4 by these resins were performed.The adsorption of Zr(Ⅵ) and Hf(Ⅵ) has been carried out in the different acidity and temperature and separation coefficients were obtained.The optimum time of adsorption equilibrium was studied and the separation coefficients in the conditions of various percentage content Hf(Ⅵ) and the elution facts of Zr(Ⅵ) and Hf(Ⅵ) were done.
