Colorimetric Determination of Chromium in Steel

Abstract

The purpose of this paper is to describe a method for the colorimetric analysis of chromium in steel which is not subject to interference by iron or alloying constituents usually present. The method is suitable for steel containing between a few thousandths and one percent chromium and is rapid, as chemical separations are not used. The basis of the method lies in the fact that ferric perchlorate, which is itself colorless, intensifies the color or the dichromate ion.
