摘要
HG/T3591-2009测定焦磷酸钾含量的方法步骤较为繁琐,本文对其进行优化,不仅省去了采用焦磷酸钠作为基准物来测定所带来的偏差,而且简化了实验步骤,提高测定的效率和准确度。
The method of HG/T 3591-2009 to determinate the content of potassium pyrophosphate was improved,which eliminated the determine deviation caused by the use of sodium pyrophosphate as the base material.The results showed that the method was simple and convenient,and had higher precision.
