Aggregation behavior of cobalt(II), nickel(II), and copper(II) bis(2-ethylhexyl)phosphate complexes in n-heptane
- Auburn Univ., AL (United States). Dept. of Chemical Engineering
The solution behavior of divalent transition metal-bis(2-ethylhexyl) phosphate (M(DEHP){sub 2}, M = cobalt, nickel or copper) complexes in n-heptane have been investigated by vapor pressure osmometry, viscometry and dynamic light scattering. The present study provides evidence that divalent transition metal-HDEHP complexes of Ni, Co or Cu can form reversed micelles and shows that molecular modeling can provide new information on the molecular structure of these reversed micellar systems. Improved knowledge of the association microstructure type, structure and composition and of the effect of phase additives on reversed micellar behavior is essential to advance the fundamental understanding of solvent extraction mechanisms.
