ABSTRACT
A simple and sensitive fluorimetric method is proposed for the determination of Cr(Ⅵ).The method is based on the oxidation of Cr(Ⅵ) to the pyronine in the sulfuric acid medium.The detection limit for Cr(Ⅵ) is 2.2μg/L,the linear range of the determination is 8.0~88μg/L.The method has been used to determine Cr(Ⅵ) in electroplating waste,electroplating solution and alloy steel samples with satisfactory results.
