中文摘要: |
采用无水碳酸钾+硼酸处理样品,电感耦合等离子体发射光谱法同时测定石灰石及白云石中7种组分,筛选了不同仪器参数条件,对各组分分别选用2条相对谱线强度适中的谱线进行分析,并以元素平均值的模式输出数据结果,测定的相对标准偏差小于0.60%.经对国家一级石灰石及白云石标准物质分析验证,结果与标准值吻合. |
英文摘要: |
After limestone and dolomite samples were treated with K2CO3 and H3BO3,ICP-AES method was applied to the simultaneous determination of 7 components in limestone and dolomite.Parameters of instrument were optimized,and proper spectral lines were chosen to carry out the analysis.The experimental results were given out by a mean value model.The RSD was less than 0.60%.Compared with the standard values of the national first grade limestone and dolomite,the measurement results were the same. |
