Abstract
The investigations on the chemistry of polyamino-polycarboxylic acids are revievecl. Special attention is given to the work going on in the Institute for Medical Research, Zagreb. The proton dissociation constants of EDT A and its C-substituted analoga are discussed and the mode of their ionization according to Tillotson and Staveley is critically reviewed. In the series of C-substituted analoga of the EDT A a lowering of selectivity for calcium is considered. The rare-earth complexes of the above mentioned compounds are considered to be essentially ionic with a certain amount of electrostatic crystal-field stabilization.
