Zusammenfassung
Zn und Mn geben gut ausgebildete diffusionskontrollierte Stufen in 0,1 M Bernsteinsäure-Lösung bei pH ∼ 3,5 bzw. 6,0. Zn entwickelt keine Maxima, während die von Mn durch 0,005% Gelatine unterdrückt werden. Da die Halbstufenpotentiale um 0,47 V auseinanderliegen, ist eine gleichzeitige Bestimmung beider Ionen möglich.
Summary
Zinc and manganese develop well defined waves in 0.1 M succinic acid at pH ∼ 3.5 and 6.0, respectively. Both the waves are diffusion controlled in nature. Zn wave does not develop any maxima while Mn does, which is suppressed by using 0.005% gelatin. Their half-wave potentials are separated by 0.47 V, which renders their simultaneous determination possible.
