| Abstract: | Ionic separation of Fe3 , Co2 and Ni2 mixed system was studied by ionic exchange resin method and inorganic precipitation method. After the separation process, titrimetric method and gravimetric analysis method were used to measure the mass of separated element. Relative deviation and relative standard deviation were calculated according to the measuring results and then suitable separation method was achieved. |
