摘要
对测定含亚磷酸钾水溶肥总磷含量的两种预处理方法即王水消解法和硫酸-过氧化氢消解法的精密度和准确度进行了对比实验,总结了两种测试方法的优劣,证实了两种方法均可用于含亚磷酸钾水溶肥总磷含量的测定。
The precision and accuracy of two pretreatment methods for the determination of total phosphorus content of water-soluble fertilizer containing potassium phosphite,namely aqua aqua digestion method and sulfuric acid-hydrogen peroxide digestion method,were compared.The advantages and disadvantages of the two methods were summarized,and it was proved that both methods could be used for the determination of total phosphorus content of water-soluble fertilizer containing potassium phosphite.
