Determination of Vitamin C by Fe~(3+)-KSCN Spectrophotometric

Duan Yu-fang

Abstract

This article describes a new method for the spectrophotometric determination of vitamin C. It is based on the red solution of [Fe(SCN)_x]~(3-x) being faded by vitamin C. In the presence of HAc-NaAc buffer solution ,the content of vitamin C in drug is determined. Beer′s Law is obeyed in the range of 0-403.2mg/L.This method has less interference and the experiment shows it is simple and rapid. The result is satisfied.
