A good indication of whether or not a certain component is a suitable entrainer from the thermodynamic point of view is the selectivity at infinite dilution. On the other hand, from the point of view of green separation processes, the amount of entrainer needed has to be minimized. Hence, the entrainer should combine a high selectivity with a high capacity. To classify selectivity and capacity of an entrainer the selectivity and capacity at infinite dilution, S-and k are used. The selectivity at infinite dilution S - is defined as the ratio of the activity coefficients at infinite dilution y It can be shown that the capacity k is also related to yf ... 

The resin is automatically regenerated when washing the column with water. No reagents are needed for the displacement of solutes hum the column and no wastes are generated. ISE is a green separation process.
