摘要：
General relationships were formulated among thermodynamic parameters characterizing complex-formation equilibria in both phases of a two-phase water-nitrobenzene extraction system and ion transfers across the interface of this system. Using these relationships and known parameters, the stability constants of Ni2+ with ethylenediamine and some N-alkyl-substituted ethylenediamines in nitrobenzene saturated with water were calculated for a temperature of 25 degrees C.
