| Abstract: | Using Perchloric acid-hydrofluoric acid-nitric acid microwave digestion samples, the contents of tungsten and molybdenum in rock and mineral were determined by ICP-MS. Mercury in polarography to damage of the human body was avided and the relative standard deviation（RSD,n= 8） were less than 2. 0%. The detection limit of the method for tungsten and molybdenum were 0. 092μg/g and 0. 065μg/g,respectively. With a national standard validation, the results agree well with the standard. Methods for detection of tungsten and molybdenum in rocks and minerals can meet the testing requirements. This method has good repooducibility with high sensitivity and high efficiency and simple operation and is suitable for the routine sample analysis. |
