摘要
通过改变尿素中亚甲基二脲测定过程中标准溶液浓度、显色酸度和显色温度的控制,改进了尿素 中亚甲基二脲测定方法,提高了测定尿素中亚甲基二脲的标准曲线相关系数、准确度和精密度。
Through changing the control of the standard solution＇ s density, the acidity and temperature of colour development, the article improves the determining method of methylene dicarbamide in urea, enhances the related coefficient, accuracy and precision of the standard curve for detemining methylene dicarbamide in urea.
