| Abstract: | Test the effect of more than fourty metal elements on separation and preconcentration. Establish a yare, quick, accurate and low cost analytic method. Results obtained by standard restoring, result contraposition of reference materials and precision tentative are satisfactory. This methodis can be applied to determination trace Au W (Au)/10 -6 :0.05-50 in geological samples. |
