氯化氢中水分测定方法的探讨

Detection method and discussion of water content in hydrogen chloride

采用重量法和卡尔菲休水分测定法对氯化氢气体中的水分进行测定。结果表明,2种分析方法测试数据准确度较高,都可以作为中控脱水的分析方法,但重量法操作简单,所需分析仪器价廉易得,在环保方面优于卡尔菲休水分测定法。

The water detection in hydrogen chloride gas with gravimetric method and Karl Fischer method were introduced. The two kinds of methods were taken as the analysis method of dewatering with the high accuracy. But the gravimetric method was better than Karl Fischer method because of simple operation and low-cost analysis apparatus.
