| 摘 要： | 通过溶剂挥发法制备了含双萃取剂(TBP-P204)的浸渍树脂，利用静态法、动态法研究其在硫酸介质中对钪的吸附行为，测得静态吸附容量21．75mg／g，绘制了吸附等温线．应用于钛白废酸，用H2O2 H2SO4洗涤铁、钛，4％HCl洗脱钪，可实现钪和铁、钛的完全分离,钪的回收率96．2％。

| Abstract: | P204-TBP impregnated resin was prepared by solvent volatilization method. The experiment studied the adsorption of scandium in sulfuric acid medium through static and dynamic method, found that the sorption capacity is 21.75mg/g and got adsorption isothermal curves .The resin can be used in titanium dioxide waste acid, utilizing H2O2+H2SO4 and 4% HCl as desorption to Fe, Ti and Sc, they can be separated from each other completely. 96% of scandium in the waste acid has been recovered. |
