Abstract

Abstract

calcium in Baotou iron ores and its slags by AAS with air-acetylene flame,interferences and its eliminated method were investigated. The samples can be decomposed by composited acids, and interferences of coexist components can be effectively eliminated using the composited inhibitors of interferences (ascorbic acid +lanthanum +niobium). The simple method for determination of calcium was established with satisfactory results.
