Abstract
An amplification method has been described for the determination of ch romium in low alloy steel samples. The well-known Leipert reaction has been coupled with a precipitate exchange reaction between lead iodate and chromium(III)-EDTA complex for amplification. Chromium is determi ned indirectly by determinig the liberated iodine and the detection of chromium is amplified twelvefold. (C) 1996 Academic Press, Inc.
