摘要
对测定总磷含量的两种预处理方法即过硫酸钾和硝酸-硫酸消解方法进行了对比实验。这两种方法均为国家环保部认可的标准方法,经实验证明其精密度和准确度都符合要求。
Determination of total phosphorus content of two pretreatment methods for persulfate and nitric acid - sulfuric acid digestion methods were compared. Both methods are approved by the State Environmental Protection Department of the standard method, proved by the experimental precision and accuracy to meet the requirements.
