摘要
针对现有国家标准方法中氟化物采样时气氟和尘氟同步等速采样不易操作的问题。通过试验提出了实用有效的改进方法 ,使测试结果的准确性提高 ,氟的采样效率从原来的 34.3%提高到 67.4%。
According to the National Standard Procedure in China,it is not easy for sampling of fluoride in gas and dust simultaneously at the same of flow rate.An improved,practical and effective sampling procedure was offered on basis of some experiments.The improved procedure increased the accuracy of the measurement results greatly,and the sampling efficiency for fluoride was improved from 34 3% to 67 4%.
