Abstract
AbstractPossible formulae of complex compounds of copper and polyacrylic acid as well as polysulfonic acid are demonstrated. The formal complex dissociation constants of the complexes with copper and acrylic acid are developed. The actual concentration of unbonded copper ions under different media conditions are calculated in terms of the formal complex dissociation constants of the most important complex compound for ultrafiltration consisting of one copper ion and two acrylic acid monomer units. As a result follows the theoretical retention capacity of membranes and the underlying limit of the concentration of metal ions for the economical application of ultrafiltration. Most of the experimental findings in the first part have been given their theoretical foundation.
