Abstract:
This paper describes a method for determination of ascorbic acid with 1, 10-Ph-enanthroline-irou (III) as a colour reagent.It involves formation of fertion when ascorbic acid reacts with a mixture of iron (III) and 1,10-Phenanthrolive, and measurement of the absorbance at 510nm. This method has been applied to assay of pharmaceutical preparation and food indurstry of Vitamin C. The results how that this method is simple, rapid and sensitive
