本文研究了伯胺N_(1923)的正辛烷溶液从硫酸介质中萃取Sc(Ⅲ)的平衡规律。通过IR,NMR测定及斜率法、等摩尔系列法研究了N_(1923)萃取Sc(Ⅲ)的机理。测定并计算了萃取反应的浓度平衡常数和热力学函数。
In this paper, the equilibrium regularity of the extraction of Sc (Ⅲ) from the sulfuric acid medium with primary amine N_ (1923) n-octane was studied. The mechanism of N (1923) extraction of Sc (Ⅲ) was studied by IR, NMR and slope methods. The concentration equilibrium constant and thermodynamic function of the extraction reaction were determined and calculated.
