应用特定烘干法测定湿氯化铵中水分的探讨

Inquiry into Determination of Moisture in Wet Ammonium Chloride by Specific Oven-Drying Method

湿氯化铵中常含有部分碱性物,影响氯化铵中水分的测定。介绍一种结合碱性物测定的烘干法来分析湿氯化铵中的水分,降低了常规烘干法测定误差,可满足生产过程分析要求。

Wet ammonium chloride usually contains some alkaline substances, which interfere with the determination of moisture in ammonium chloride. An oven-drying method is presented in combination with the determination of the alkaline substances for the analysis of moisture in wet ammonium chloride, reducing the error in the routine oven-drying method, meeting the analytical requirements in the production process.
