| Abstract: |
| Adding quantificational NaCl to precipitate Ag + as AgCl when crude palladium is dissolved with nitric acid Most of AgCl is separated by filtration Palladium in filtrate is deoxidized to crude palladium again, and then using the method of [Pd(NH 3) 2]Cl 2 to purify palladium At acidifying process of the purification, silver is formed into - by increasing concentration of chloric acid Through filtrating and washing, - is separated thoroughly and it will get pure palladium |
