It is based on the principle of separation or purification by chromatography Al2O3 is used as adsorbent. The mixture to be separated is taken in suitable solvent and applied on the coloumn.They are eluted out using suitable solvent. The weakly absorbed component is eluted first ,then the more strongly adsorbed on. This method is suitable for those elements which are available only in minute quantity and these impurities are not very much different in their chemical behaviour from the element to be purified
