Abstract
The activity coefficients of bis(2-ethylhexyl) phosphoric acid, HDEHP, in n-dodecane in the concentration range 1 × 10−3 − 1 have been evaluated from liquid-liquid distribution studies of Eu+3, Tm+3 and Ca2+. The deviations from ideality have been interpreted in terms of solute-solute weak interactions, where the interacting solute species is the HDEHP dimer.
