DETERMINATION OF MnO, CaO, MgO, AND P₂O₅

Study on the Chemical Analysis of Sand Iron and IImenite-III

Abstract

In the report (I) and (II), the methods for the determination of total Fe, FeO, TiO₂, SiO₂, Al₂O₃, V₂O₅, and Cr₂O₃ in sand iron and ilmenite were developed. In this report, a simple photometric or volumetric methods is described for the determination of MnO, CaO, MgO, and P₃O₅ which are contained in sand iron and ilmenite. MnO is determinedby photometric or volumetric methods with the (NH₄)₂S₂O₈. CaO and MgO are determined by the EDTA titration method. P₂O₅ is determined by photometric method using the molybdenum blue.
