阐述了卡尔费休法测定固体水分测试方法中实验室温湿度,固体在溶液中的溶解速度等影响因素。通过样品的事先溶解,对加入溶剂溶液质量的准确称量,使用不同型号的水分仪等几个方面对酒石酸钠固体水分进行测定,提出了固体样品测定的一些改进办法,部分解决了固体水分测定中重现性差,环境湿度要求较高的问题。
The influential factors such as the temperature and humidity in the laboratory, the dissolution rate of the solid in the solution and other factors in Karl Fischer method are described. Through the prior dissolution of the sample, accurate measurement of the quality of the added solvent solution, the use of different types of moisture meter and several other aspects of sodium tartrate solid moisture was measured, put forward some solid samples of the sample to improve some of the measures to solve part of the solid moisture determination Poor reproducibility, high humidity requirements of the environment.
