Title: Spectrophotometric determination of trace cerium with foding reaction
Abstract: AbstrcatThe fading oxidation of Dithizone by hydrogen periodate in sulfuric acid using cerium(Ⅳ) as a catalyst was investigated in this paper. The reaction order and the apparent activation energy were determined. A new method for the determination of Ce has been established. The limit of detection is 1.9×10~(-9) g/mL of Ce(Ⅳ) and the linear range is 0~150 ng/mL of Ce(Ⅳ). The method has been used to determine trace Ce in hair samples.
