| Abstract: | In thin paper a new vanalytis speetrophotoment method has been developed for the determination of tract vanadium,winch based on vuanum C existence,using a new indicator neaction that vanachum catalyre potissunt hromate oxidezats methyl green and decolours it. The limit of detection is 2 s1X10g/ml. The ranges of determination is 0-16ng/25ml. It is satisfactory in tpply thin method to the analysis of nature Water and human hart samples. |
