摘要

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, pH 3~5, wavelength 396 nm;Determined the content of Fe~(2+), Obtained the content of Fe~(3+) 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.
