摘要
工业氨水要求氨含量在20%~22%,尿素含量需小于2%,分析工业氨水中尿素含量的方法属于常量分析。当前常量尿素分析方法有对二甲氨基苯甲醛比色法以及甲醛比色法两种,通过对比两种方法,选出最为恰当的分析方法。
Industrial ammonia water requires an ammonia content of 20%to 22%,and a urea content of less than 2%.The method for analyzing the urea content in industrial ammonia water belongs to constant analysis.There are currently two methods for analyzing constant urea:the p-dimethylaminobenzaldehyde method and the formaldehyde method.By comparing the two methods,the most appropriate analysis method was selected.
