| Abstract: | Micro - silver in geological samples are determined by using the method of graphite fire atomic absorption spectrum. It realized the best equipment conditions by using NH 4 IrCl 6 as the matrix modifier. Under the condition of sampling 0.2000g and constant volume of 25 mL, the method detection limit is 0.010ug/g. As tested by national standards, its accuracy （ RE% ） is less than 10%, and the precision （ RSD% ） in 10 times determination are less than 10%. |
