Interaction in the mixed adsorption monolayer at the liquid/liquid interface

The FT-IR spectrum for two chelating metal ion extractants: 2-hydroxy-5-nonylacetophenone oxime (HNAF) and 1-phenyldecane-1,3-dion (b-diketone) and decanol used as a modifier were presented. Moreover, two equimolar binary mixtures of extractant/extractant and extractant/modifier type were considered. The interaction between two extractants or the extractant and modifier molecules adsorbed at the mixed adsorption monolayer formed in extraction systems were discussed. The usefulness of the spectral technique (FT-IR) for studying the formation of a new ligand association adducts between the extractants and modifiers or two extractants in a binary mixture as well as a formation of self-association adducts of the extractants molecules were presented.
