Paper Title:
Study on Determination of the Content of Fe2+,Fe3+ in Medicine Haematitum with Different Characters
  Abstract

Objective: Establishment the iron (Ⅱ), iron (Ⅲ) the content determines separately method in haematitum.Methods: Sample decomposition with hydrochloric acid and potassium fluoride. Determined the content of iron in different characters mineral medicine haematitum by UV-vis spectroscopy, pH3~5, wavelength 396nm;Determined the content of Fe2+, Obtained the content of Fe3+ by concentration difference. Results: This method is easy to do.The accuracy is good.The returns-ratio is high.The method may take the haematitum quality the control standard.
