Quantitative extraction of CdII has been achieved from acetate buffer at the pH range 6.5-7.5. The effects of pH, stripping agents,

CdII has been separated from synthetic binary and multi-component mixtures containing various elements by exploiting the differences in pH for extraction and elution. The method effectively permits sequential separation of CdII from synthetic mixture containing its congeners CuII , HgII , Znll and PbII of same analytical group.
