This document specifies the determination method of oxidation calcium and oxidation mg in high titanium slag and rutile. It is suitable for the determination of the content of these elements in high titanium slag and rutile. The determination range is oxidation calcium: 0.10%~ 7.0% and oxidation mg: 0.020%~ 8.0% respectively. The method summary includes dissolving, heating, digestion, absorption photometric determination and other steps. Reagents include perchloric acid, hydrofluoric acid, muriatic acid, strontium nitrate solution, etc. The instrument requires the use of AtomicAbsorption Spectroscopy with characteristic concentration and precision indicators.
