臭素並びに沃素メタノール溶解に対する成分介在物の挙動の比較

Abstract

In order to clarify whether the methanolic bromine method, proposed by the author, is suitable for the purpose of oxide separation or not, the behavior of individual inclusion components, commercial reagents or materials synthesized by the author was compared by treating them with methanolic bromine and iodine at ordinary temperature and at 60°C, respectively. The results show that crystalline or amorphous, silica and alumina, manganese sulfide, non-crystalline, iron oxides, and nitrides of aluminum and silicon, behave similarly in both methods, but manganese monoxide is more unstable in bromine than in iodine, solution and iron sulfide, nitrides of iron and manganese are more or less stable in iodine treatments, hence the iodine method is more subject to interference by these in the case of oxide determination than the bromine method.
