In order to determine the 'free' metal ion concentration in aqueous solutions the so-called Wageningen Donnan Membrane Technique (WDMT) has been developed. This involves a continuous flow system in which the donor side and the acceptor side of the WDMT cell are continuously flushed with solution across the membrane. The new cell design allows pseudo equilibrium to be reached for the free metal ions via a Donnan equilibrium across a negatively charged ion-exchange membrane within a reasonable time span. The donor solution contains both 'free' and complexed metal ions. The concentration of the cations in the acceptor solution is either equal to the concentration of the 'free' cation concentration in the donor solution, or it can be calculated...
