| Abstract: | A fast speed precise method is proposed for the direct determination of 14 trace in 99. 0-99. 993% silver by direct-current arc AES, with chloride ion deprived of the precious metals standard solution most of the matrix interference can be eliminate. The recovery for the method is 91. 5-110% and the realive standard deviatio.n is 6. 0-14. 2%. |
