摘要
考察了伯胺N_(1923)的CCl_4溶液从硫酸介质中对镧(Ⅲ)的萃取机理,探讨了水相组成与温度对萃取的影响,求得萃取平衡常数lgK_(ex)=3.45。
The extraction of La(Ⅲ) from sulfuric acid with N_(1923)一CCl_4Solution has been studied.The experimen tal results indicate that the extraction mechanism is as follows。1.5(RNH_3)_2SO_(4(0)) Where(o)represents the organic phase and Kex the equilibrium constant , logKex =3.45. The influences of acidity,temperature on the extraction were also discussed。
