摘　　要：介绍了在制定《铁矿石化合水含量的测定卡尔费休滴定法》国家标准中所开展的试验工作。研究了用卡尔费休滴定法测定铁矿石中化合水的电位滴定分析技术,重点研究了载气流量和加热温度的控制、标定方法的比较以及试验验证。A series of experiment works regarding instituting national standard of ＂Iron ores - Determination of combined water -Karl Fischer method＂ are expounded. The electrometric titration technique with determination of combined water content in iron ores using Karl Fischer method has been studied. The analysis method of combined water has been established via controlling flux of carrier gas and heating temperature, comparison of two standardization methods, and organizing verification test.
