Amperometric determination ot bivalent tin with dichromate
(Springer-Verlag, 1963) G.S. Deshmukh; S.V.S.S. Murty
An amperometric determination of tin with potassium dichromate has been described. The advantage of the cathodic polarograms of Cr2O27- and Sn2+ in formate media was taken and titrations were performed at -0.8 V vs. S.C.E. at pH ≈3.0. It is shown that tin upto 10 mg may be determined accurately within the limits of experimental errors. © 1963 Springer-Verlag.
Polarographic behaviour of zinc in sodium formate solution
(Springer-Verlag, 1966) G.S. Deshmukh; A.L.J. Rao; S.V.S.S. Murty
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.
Polarography of divalent manganese in sodium formate solution
(Springer-Verlag, 1963) G.S. Deshmukh; A.L.J. Rao; S.V.S.S. Murty
A well defined wave for manganese in 1 M sodium formate solution is reported and its use for the determination of microquantities of the element is indicated. Several foreign ions studied do not cause any interferences. © 1963 Springer-Verlag.
