| Abstract: | A new system has been developed for the extraction of microamounts of silver by using N-Cetylpyridinium Chloride- Buty1 acetate in the medium of 1mol/L HCl, and the Ag extracted into the organic phase is determined directly by AAS. This method is simple, rapid and sensitive, and about 30 coexisting ions do not interfere with the determination, This method is used for the determination of micro amounts of Ag in geochemical samples successfully. |
