Abstract
The distribution coefficient (Kd) of some metal ions have been determined at various pH values on stannic (IV) arsenate cation exchanger. Based on this study, the separation of some important pairs of metal ions has been achieved. The separation of Fe(III) from Ni(II), Co(II), Mn(II), Ca(II) and Al(III) have been achieved quantitatively in some synthetic mixtures. The quantitative separation of Fe(III) from some appetizers and from biological material has also been achieved. The method is simple, rapid and highly selective with good accuracy and precision within the experimental error range (±2%).
