摘要
对国家标准GB/T 1574—2007中测定五氧化二磷的2种方法进行了分析对比。分析结果表明,高氯酸-氢氟酸熔样法操作较简便,其测定结果准确可靠,同时由于其采用测试氧化钾所用的原液,故节省了时间,提高了检测效率。
The two determination methods of phosphorus pentoxide in GB/T 1574 2007 were compared. The results show that it＇s more simple and accuracy with the method of using perchloric acid and hydrofluoric acid, which can also save time and increase the detection efficiency by using testing stock solution of potassium oxide.
