| 摘 要： | 在铁、铝、钙、镁、硅共存的情况下测定钙，共存组分铁、铝、镁、硅都将干扰钙的测定。根据硅、铁、铝等干扰组分与掩蔽剂反应的比例关系，分析计算出掩蔽剂的适宜加入量。实验结果表明，对干扰组分定量掩蔽，可提高测钙的准确度。

| Abstract: | In silicate analysis, the determining accuracy of calcium was disturbed by the content of Fe, Al, Mg and Si. For resolving it, the proportion relation of masking agent and interfering substance (Fe, Al, Mg and Si) was analyzed, and the suitable content of masking agent was brought up also. By experimental verification, it has been found that the determining accuracy of calcium was improved by quantifying the content of masking agent. |
