| Abstract: | A auto-potentiometric titration method is developed for the determinationof total iron in FeZO3 by titration with Ce(SO.),.The sample is dissolved in HCI and is reduced by copper.The htrahon is followed by Pt and SCE.The method show good accuracy and precision. The-method avoids the use of neither HgC12 nor KZCrZO,.It is a polluhon-free method for determination of iron. |
