粉状磷酸一铵产品质量标准为 ZB/ TG2 10 0 990 ,在执行该系列标准对我厂磷酸一铵产品质量进行检验的过程中 ,多次发生分析结果的争执。本文通过对总氮测定试样制备 ,湿基状态下各有效组分测定值是一个动态值 ,枸溶磷的提取过程是不完全的提取 3个方面的问题进行描述 ,并提出相关的意见
The quality standard of powdered monoammonium phosphate is ZB / TG2 10 0 990. During the implementation of the series of standards, the dispute of analytical results occurred in the process of testing the quality of monoammonium phosphate product of our factory. In this paper, the determination of the total nitrogen determination of the sample, the wet-based state of the measured value of each active ingredient is a dynamic value, the extraction process of citric acid phosphorus is incomplete extraction of the three aspects of the problem described and made relevant comments
