| Abstract: | With capability of intense selective adsorption of trace silver in the presence of acidic medium, mercapto-cotton-fiber is able to remove disturbing elements effectively to reach multiple enrichment of trace silver. In case the titration of disulfo-hydrazone is used to determine trace silver, the examination limit is 0.005kg/ml. |
