| Abstract: | The adsorption characteristics of Zirconium (Zr) and Hafnium (Hf) on self-synthetic P507 solvent impregnated resins has been investigated. Based on the above experimental results, a method for the extraction separation and spectrophotometric determination of Zr (Ⅳ) and Hf (Ⅳ) was developed, and the interferences of coexisting ions and the stabilities of the ion-exchange column have also been discussed. |
