Polarographic behaviour of zinc in sodium formate solution

Abstract

A polarographic determination of Zinc can be successfully performed in 1 M sodium formate solution (pH 7.0) as supporting electrolyte using 0.005% of gelatin as maximum suppressor. Well defined waves are obtained for 1-6 mM of zinc and various anions do not cause any interference. The method is also suitable for the determination of zinc and mangenese in presence of each other. © 1966 Springer-Verlag.
