高频红外碳硫分析仪对萤石矿中硫含量的测定

Determination of Sulfur Content in Fluorite Ore by High Frequency Infrared Carbon Sulfur Analyzer

采用高频红外碳硫分析仪(HFI-C/SA)对萤石矿中的硫含量进行检测。称取合适质量的烘干萤石矿试样,加入助溶剂后进行检测。批次实验结果表明,使用HFI-C/SA检测萤石矿中的硫,其最小检测质量分数为0.00011%,精密度在4%~5%,且分析快捷、结果准确可靠,检测精密度能满足萤石矿中硫分析检测要求,说明采用此法测定萤石矿中硫具有很好的可行性。

There is only sulfuric acid standard solution titration for the determination of bicarbonate and bicarbonate in Part 4 of The Analysis of Water Soluble Salts in Forest Soils(LY/T 1251-1999).Weigh the dried fluorite sample of appropriate quality,and add the appropriate quality of cosolvent for testing.The batch test results show that the minimum detection concentration of HFI-C/SA is 0.00011%,and the precision is between 4%and 5%,and the analysis is fast,the results are accurate and reliable,and the detection precision can meet the requirements of sulfur analysis in fluorite.It shows that the method is feasible to determine sulfur in fluorite.
