摘要
文章介绍了一种用于水分含量测定的方法——卡尔.费休法,分析了该法的测量原理,讨论了样品的酸碱性、样品处理、样品量的多少及卡氏试剂的滴定度、副反应、漂移值、电极感应等多个方面因素对卡氏水分测定仪测量准确度的影响,为水分分析测试研究人员提供参考。
The Karl Fischer method for determining water was introduced in the paper. The determining principal was analyzed. Several effects on the accuracy of Karl Fischer method for determining water which were the pH of sample, the weight of sample, sample handling, the titre of Karl Fischer Reagents, by-reaction, drift, electrode were discussed.
