    Polarographische Untersuchung der Substitutionsreduktion des Kupfer(II)-äthylenglykol-bis-(2-aminoäthyläther)-N,N,N′,N′-tetraacetat-Chelats in Gegenwart von Calciumion und Anwendung zur Calciumbestimmung neben Magnesium

    Calcium ion facilitates the reduction of copper(II)-ethyleneglycol-bis-(2-aminoethylether)-N,N,N′,N′-tetraacetate chelate and provokes a new wave at a more positive potential. The properties of the reduction w...

    Polarographische Untersuchung der Substitutionsreduktion des Kupfer(II)-Äthylendiamintetraacetat-Chelats in Gegenwart von Calciumion

    The reduction of copper(II)-EDTA chelate at the drop** mercury electrode is facilitated by calcium ion, because the EDTA anion liberated by the reduction will react with that ion. The theoretical prediction ...
