摘要 以电感耦合等离子体原子发射光谱(ICP-AES)法测定石灰中二氧化硅和磷含量,通过实验对仪器进行优化,确定分析谱线、称样量等分析条件,采用标准溶液绘制校准曲线,通过标准样品验证,加标回收率在101%~113%,相对标准偏差为0.004%~0.006%(n=5)。方法实用,结果满意。 The content of silicon dioxide and phosphorus in lime was determined by ICP-AES, The instrument was optimized by experiments, and analysis conditions such as spectral line and sample size were determined. The calibration curve was drawn with standard solution. After verification of the standard sample, the standard addition recovery rate was 101%-113%, and the relative standard deviation was 0.004%-0.006%( n =5).The method is practical and the results are satisfactory.
