【Abstract】 The effect of samples pretreated by microwave digestion, wet digestion and high temperature ashing were compared, and the content of potassium, sodium, calcium and magnesium in perfluoroether rubber(FFKM) was determined by high temperature ashing-atomic absorption spectrophotometry. The results showed that the detection limit, precision and recovery of added standard of the developed method were satisfactory, the results of test were proved to be accurate and reliable.更多还原
