    Abstract: A determination method of silver in soil by graphite digestion procedure combining ICP-MS/MS Ammonia mode was established. ICP-MS/MS hydrogen, oxygen and ammonia model measurement results were compared. The results showed that ammonia mode could completely remove polyatomic ion interferences. Two isotopes of silver were measured simultaneously and National standard substances were analyzed. The results proved that the method was accurate and reliable. The detection limit of the method was 0.003 mg·kg-1, and the precision was less than 3% (RSD%). This method used ICP-MS/MS technology completely to remove polyatomic interference online, and 107Ag and 109Ag isotope results could double verified the data. Compared with other works, this method saves the pre-processing time and has higher accuracy.
