Abstract
A method has been developed for the standardization of Indian ayurvedic drugs containing iron, using inorganic ion exchange material antimony (V) arsenosilicate cation exchanger. The iron present in the drug was absorbed quantitatively on the columns of the exchanger, eluted with a suitable solvent and then titrated against a standardized EDTA solution.
