硝酸钡

The working conditions of equipments, the mediums and their concentrations, and the interference of coexisting ions were investigated. The results showed that when the flame was shielded with oxygen enriched, the barium in lapis lazuli could be determined using calcium nitrate as releasing agent in 5% nitric acid. The obtained results were satisfied.
