摘要
提出了锑酸钠样品锑量测定中的还原剂的改进,用滤纸作为还原剂,将五价锑还原至三价锑,然后在盐酸介质中用硫酸铈标准溶液滴定。加标回收率为99%~101%,精密度好、测定准确、可靠。
The paper is about the improvement of determination method of antimony in sodium antimonite. Use the filter paper as the reducing agent to make the pentavalent antimony becoming the trivalent ones, and then titrate with cerium sulphate standard solution in hydrochloric acid medium. Its recovery rate is in the range of 99%-101%. The method owns good precision, accurate and reliable determination.
