本文研究了0.69,0.92及1.15M三辛胺-甲苯溶液从盐酸介质中对氯化铀酰的萃取。通过实验及热力学计算,求出参加萃取反应的各组分的浓度及活度系数,从而得出了三辛胺萃取盐酸和氯化铀酰的热力学平衡常数。其值分别为:K_4=1.46×10~3,K_5=(2.48-3.79)×10~5。
In this paper, 0.69,0.92 and 1.15M trioctylamine - toluene solution from hydrochloric acid medium uranyl chloride extraction. The thermodynamic equilibrium constants of extracting hydrochloric acid and uranyl chloride from trioctylamine were obtained through experiments and thermodynamic calculations. The values are: K_4 = 1.46 × 10 ~ 3, K_5 = (2.48-3.79) × 10 ~ 5.
