| 摘要: 采用单液滴法考察了水相酸度、钴(Ⅱ)在水相和有机相的浓度、萃取剂浓度以及温度和介质等因素对萃取速率的影响。结果表明,萃取反应机理是两步界面连续反应。文中对介质的影响也作了讨论。 |

Abstract: The kinetics and mechanism of the extraction of Co2(H) from sulphate medium with HEH(EHP) in kerosene were studied by mean of single drop method at 25℃. The experimental results indicate that the extraction process is controlled by the following interface reaction. 
where (0) and (i) represent the organic phase and interface respectively. The influences of sulphate, chloride and nitrate concentration on the extraction.rate were also discussed. |
