摘要
难溶矿石碱熔后,以铋磷钼蓝光度法测定磷,直接加掩蔽剂消除硅、砷的干扰。与国家标准方法检测结果相比,并用国家标准物质比对,结果表明,本法检测结果稳定、可靠,可操作性强,满足分析要求。
Ore sample is dissolved with alkali, and disturbing of silicon and arsenic are directly eliminated by adding masking agent, low content phosphorus in the ore can be determined by bismuth phosphomolybdate blue spectrophotometry. Contrasted with the determination results of national standard method and national standard materials, the results are stable and reliable. The method can be operated easily, and meet the requirement of analysis.
