Transport of electrolytes through charged membranes - on the relations between the independent transport coefficients

In this work, we present the relations between the transport coefficients for the system multi-ion solution/ion-exchange membrane resulting from the neglecting of ion-ion interactions. We present one of the possible sets of the practical transport coefficients for that system, and we show how to obtain the relations between them. Other sets and relations of practical coefficients can be easily derived following the way described here.
