Abstract
Paper chromatographic separation of copper and aluminium in aluminiumβbronze alloy has been achieved by ascending filter paper strip method, the solvent employed being a mixture of 75% nβbutanol, 15% concentrated hydrochloric acid and 10% of water. The separated metal ions were extracted and quantitatively determined colorimetrically using sulphoβdichlorohydroxyβdimethyl fuchson dicarboxylie acid (Chrome Azurol S) as a colorimetric reagent. The results of analysis have been found to be satisfactory.
