| Abstract: | According 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. |
