Title: Determination of Trace Vanadium by Kinetic Catalytic Spectrophotometry
Abstract: A new spectrophotometric method for the determination of trace amount Vanadium was developed.It is based on the fact that V(Ⅴ) can catalyze the decolorizing of methyl green with KIO_4 in the medium of H_3PO_4 and Vc.The linear range of Ⅴ(V) is 0.1~1.0 ng·mL~(-1),and the determination limit is 2.90×10~(-10)g·mL~(-1).The method has been used for the determination of trace Vanadium in celery and wheat with satisfactory results.
