Title: Determination of Trace Vanadium(V) by Kinetic Spectrophotometry
Abstract: A new sensitive kinetic method for the determination of V(Ⅴ) based on its catalytic effect on the oxidation of PAN by potassium persulfate in HAc medium is proposed.The optimum condition and kinetic parameters have been investigated. The detection limit is 2.62×10~(-9)g/mL and the linear range is 0.0~40.0 μg/L V(Ⅴ).The method has been applied to the determination of trace vanadium(Ⅴ) in rice, wheat and bean with satisfactory results.
