Abstract: | The stability constants of mononuclear (1:1) and binuclear (2:1) chelates of the Ag-HDPTA and Hg(II)-HDPTA systems (HDPTA = 2-hydroxy-1,3-diaminopropane-N,N,N',N'-tetra-acetic acid) were evaluated from pM and pH data, using a method proposed earlier by Ringbom and the author. The determinations yielded the following stability constants (concentration): The use of the reagent for the analytical determination of silver and mercury(II) ions is also discussed. |
