Abstract

The novel method for the spectrophotometric determination of trace amount of iron (III) after separation of its BPA complex by adsorption on microcrystalline naphthalene is described. The epsilon/ sub max/ of the DMF solution of the adsorbate containing iron (III)- BPA complex at lambda/sub max/ 437 nm has been found to be 4.47 X 10/sup 3/. The effect of variables and interfering ions on the efficacy method has been studied. Sensitivity (in Sandell's notation) is 1.25 X 10/sup -2/ micro g of iron (III)/cm/sup 2/ and at a mean absorbance of 0.40000 is 1.25%. The method is useful for the analysis of standard reference materials and environmental samples. The results are comparable with those obtained using ortho phenanthroline.
