| Abstract: | A method for separation and enrichment of trace silver with sponge has been studied. It is found that its adsorption selectivity and concentration effect for the complex of silver and 1,10-phenanthroline are very good. In the presence of EDTA the other metal ions can't be adsorped. Ag (phen) 2~+ can be eluted quantitatively by 1 mol/L HNO_3 and then determined with spectrophotometry, with recovery 96.3 and relative error 1.1%. |
