Scope
Scope: This document specifies the method for determining the content of iron(III) oxide in bauxite; Main technical content: The sample is dissolved by alkali fusion and extracted with hydrochloric acid. In a solution with a pH of 8 to 10, iron(III) forms a stable yellow complex with sulfamic acid, with a maximum absorption at a wavelength of 425 nm. The absorbance value is proportional to the content of iron(III) oxide, and the content of iron(III) oxide is determined by photometry.
