摘要
用石墨衬瓷皿替代铂坩埚,碱熔分解硫酸钡矿样,熔样条件为750℃,保温20min。该分析方法成本低,分析结果稳定、可靠。适用于中小型矿山生产过程中硫酸钡的测定。
Platinum crucible was replaced by chinaware with graphite liner at750℃ and heat preserving for 20 min while melting the samples. The assay method is lower in cost with a stable and dependable result, fitting for the barium sulfite determination for processing in middle to small enterprises.
