| 英文摘要 | Leaching of an extracted vanadium residue in sodium sub-molten salt medium was investigated. The significant effects of reaction temperature, particle size of residue, reaction time and NaOH-to-residue mass ratio on vanadium extraction were studied. By the orthogonal experiment study, it can be concluded that the impact order of factors is Tr TR according to the significance to the leaching process. Under conditions of reaction temperature 170掳C, NaOH-to-residue 4:1, stirring speed 700 rpm, particle size -74 渭m and reaction time around 180 min, leaching efficiency of vanadium obtained is higher than 90%. And, the leaching process of vanadium, with activation energy 27.69 kJ·mol-1, is controlled by the chemical reaction-controlled as the following rate equation. ln(1 - X) = -kt. |
