摘　　要：研究了钒（Ｖ）与氯代磺酚Ｓ的退色反应，确定了最佳测定条件，简便地消除了共存离子干扰。方法具有较好的选择性，钒量０～９０μｇ／５０ｍＬ符合比尔定律。用于钢铁中钒的测定，简便、准确。In the paper we studied the oxidation-color fading reaction of vanadium (Ⅴ) with sulfochloro pheno S. The selectivity of this method is very good.Beer'S law is obeyed from 0 to 90μg Ⅴ(Ⅴ) in 50mL.The mechanism of the color fading reaction has been studied.The method is simple and gives accurate and reproducible results when applied to the determination of vanadium in iron-steel samples.
