| Abstract: | The extraction behaviour of (NH4)2SO4-biacetyl dioxine-ethanol system was studied and proper conditions were selected. It shows that the complex of Co2 and biacetyl dioxime can be extracted into the ethanol phase, the precipitate of Ni2 and biacetyl doixime floats between the two phases while the Fe3 is left in the aqueous solvent at PH>5. It is concluded that Co2 can be separated completely from Fe3 and Ni2 in the system. |
