| Abstract: | The main sources of silver-containing liquid waste and 5 methods for recovering the silver from them are elaborated systematically. Among the five methods, adsorption has the advantages of easy operation, low energy consumption, large adsorption capacity, etc. The electrochemically-oxidized active carbon fibers (ECF) and naphthylenediamine polymer containing free amidogen are excellent adsorbents which have appeared in recent years, the adsorption capacity of which can be as high as 1360 mg/g and 1924 mg/g respectively, which show a broad prospect for their application in the field of silver extraction and recovery. |
