On the properties of solid and liquid ion exchangers–VI Application of a simple model to some ion exchange reactions on dinonylnaphtalene sulfonic acid in different solvents and for different cations with heptane as solvent

A simple model assuming three kinds of micelles has been applied to the K + H + exchange on dimonylnaphtalene sulfonic acid (HDNNS) in the solvents: chloroform, carbon tetrachloride, nitrobenzene and isooctanol, to the Ca 2+ H + exchange in heptane, nitrobenzene and isooctanol. In heptane the following exchanges were also studied: Ag + H + , Cu 2+ H + , Ni 2+ , Fe 3+ H + and Al 3+ H + . Also the water uptake was studied for Ca 2+ H + and K + H + in nitrobenzene as solvent. The three parameters, found to fit each system are collected in Table 2. At present no simple rationalization of these constants seems possible.
