摘要
用滴定微量量热仪测定了 P538煤油液在 2 5℃时从硫酸钠介质中萃取 Co( )过程的热功率 -时间曲线 ,得到了该萃取体系的反应热 ,结合文献的工作 ,计算出了不同温度下的萃取平衡常数及有关的热力学函数。
The microcalorimetric monitor was used in the P538/Co(Ⅱ) extration system. Its reaction heat was determined as ΔrH=-168 kJ.mol from the power-time curve at 298 K.Based on the heat and the equilibrium constant reported before ,the equilibrium constant and thermodynamic functions at different temperatures were also calculated.
