摘要：
The extraction of Co(II) and Ni(II) from sulfate solution with Cyanex 272 in kerosene has been studied by titration microcalorimetry. The heats produced in the reaction processes were determined by the power-time curves and the Delta H-r(m)theta values at 298K were identified. The extraction equilibrium constants and thermodynamic functions at different temperatures were calculated.
