摘要
本文提出了用离子选择性电极测定水泥及原料中K_2O、Na_2O含量的一种新方法。K_2O含量直接用钾电极测定;而在钠电极测定Na_2O含量时,则利用多元线性回归原理,对结果进行校正。该法简化了分析操作,提高了测定的准确度,用于样品分析,结果令人满意。
The paper reports a new method to determine K_2O and Na_2O in cement and its mate-rial. According to the principle of multivariate linear regression, a programme is devised. The contentof K_2O in the sample is determined directlyby using the potassium electrode, and the result when thecontent of Na_2O is determine by using the sodium electrode is correct. The analytical operation issimplified, and the accuracy of the result is raised. The results of determining the synthetic sampleand the real one are quite satisfactory.
