火焰光度法在水泥碱含量测定中的应用

Application of flame photometry in Alkali content determination of cement

通过火焰光度法测出5种水泥标样的碱含量与其标准值对比,证明该方法测定水泥碱含量是准确的。介绍了氧化钾、氧化钠标准溶液的标定及火焰光度法测试的基本步骤,并阐述和分析该试验的注意事项和控制要点,以减小测量误差,确保检测结果的准确性。

The Alkali content of five kinds of cement standard samples were determined by means of flame photometry, and the determination results were compared with the standard values which verify the contents out of flame photometry are correct. An introduction was made on the calibration of standard solution of potassium oxide and sodium oxide, and on the procedures of flame photometry. The authors also analyze the issues in need special attention and key control points during test to minimize measuring error and guarantee the accuracy of testing results.
