Preparation of Pd(Ⅱ)-Imprinted Polymer and Study on Its Property of Separation and Enrichment of Palladium(Ⅱ)

Pd(Ⅱ)-imprinted polymer was prepared by the technique of surface modification of silica gel. Specific property of the Pd(Ⅱ) ion imprinted polymer was studied and compared with those of non-imprinted polymer. Values of maximum static adsorption capacity of the imprinted polymer and non-imprinted polymer for Pd(Ⅱ) ion were found to be 26.71 mg·g-1 and 10.13 mg·g-1 respectively,which showed that much higher selectivity was attained by the imprinted polymer for Pd(Ⅱ) as compared with the selectivity of the non-imprinted polymer. The proposed method was used as an effective method for enrichment of Pd(Ⅱ) ion in its ICP-AES determination in geological samples. Results obtained were in consistency with the standard values.
