摘要
参考磷酸在345~356℃时有强腐蚀性的特点,采有硫磷混合酸消解矿样.能使样品消解完全。本方法经加标校核证明.检测结果重现性好,准确度高。
Accordlng to the strong corrosion of phosphoric acid between 345 and 356 centigrade, the author decomposed the sample with sulfur-phosphorus mixture acid. It showed that the sample could be dissolved completely in this process. This analysis method was verified well accuracy and repeatability by running standard addition and recovery experiments.
