摘要

利用已知的热力学参数，对ML+络合阳离子(M+ = Na+， K+， Rb+， Cs+;对L =二苯并-24-冠-8)在25℃水-硝基苯萃取体系中的萃取效果进行了评价。这些常数按Na+ <K + & lt;Rb + & lt;Cs+，即按碱金属阳离子的结晶半径增大的顺序排列。

Thermodynamic parameters characterizing complexes of alkali metal cations with dibenzo-24-crown-8 in the water—nitrobenzene extraction system

By using known thermodynamic parameters, the Briggs logarithms of the individual extraction constants for the ML⁺ complex cations (M⁺ = Na⁺, K⁺, Rb⁺, Cs⁺; L = dibenzo-24-crown-8) in the water—nitrobenzene extraction system at 25 C have been evaluated. It has been found that these constants increase in the order Na⁺ < K⁺ < Rb⁺ < Cs⁺, i.e. in the order of increasing crystallographic radii of the alkali metal cations.
