水体中超标的Cr(Ⅵ)是有害元素,它对皮肤有刺激性,能使皮肤溃疡,已确认为致癌物,能在体内蓄积.因此准确地测定环境水样中的Cr(Ⅵ)对防止环境污染,保障人体健康,有着十分重要的意义.近几年来,采用动力学分光光度法测定痕量铜、铁、银等元素的报导很多,但灵敏度较高的动力学光度法测定六价铬的报道很少.本文发现在微酸性介质中,
Cr (Ⅵ) is a harmful element which is irritating to the skin and can make the skin ulcer, which has been confirmed as a carcinogen and can accumulate in the body.Therefore, the accurate determination of Cr Environmental pollution and human health are of great significance.In recent years, there are many reports on the determination of trace amounts of copper, iron, silver and other elements by kinetic spectrophotometry, but the kinetic spectrophotometric method with high sensitivity has been widely used in the determination of hexavalent chromium Reported very little.This paper found that in a slightly acidic medium,
