| 摘要: 本文用分配法研究了以正己烷、环己烷、苯和氯仿作稀释剂时HEH[EHP]对Cr(Ⅲ)的萃取,提出了萃取反应平衡式及平衡常数;对在不同稀释剂中HEH[EHP]萃取能力发生变化的现象作于讨论. |

| Abstract: The extraction of Cr(Ⅲ)from sulfate solution with HEH[EHP] in n-hexane, cyclohexane, benzene or chloroform has been studied. The experimental results show that these extraction equilibria may be represented by Cr(OH)2++1.5H2A2(o)=CrA3(o)+H++2H2O
The values of lgK0x for various diluent were calculated to be -2.61(n-hexane), -2.91(cyclohexane), -3.21(benzene) and- 4.23(chloroform) respectively. The effects of the solvent on the extraction were also discussed. |
| Keywords: extraction chromium(Ⅲ) mono(2-ethylhexyl)2-ethylhexyl phosphonate |
