Determination of Trace Element in Galena Ore using Polarography Techniques

Manju Rathore, Dr. Jyotsna Shukla

Abstract :

 Galena is a main source of Silver.it is associated with other element like Pb ,Cu ,Cd, SN, Ni, and Zn ,which is present in trace element . Direct current Polarography (DCP),Differential Pulse Polarography (DPP),have been successfully handle are determination of metal in ores and mineral Polarographic and Voltammetric methods are not only accurate and sensitive but are easy to handle and economic. They are highly useful and workable under ordinary laboratory conditions. In favorable cases they have proved to be superior to other techniques which are in use for such type of a purpose. Ammonia–ammonium chloride buffer as supporting electrolyte and 0.001% gelatin as maximum suppressor in a polarographic cell and final volume were made up to 100 ml with distilled water. The sample indicated the presence of –0.06/–0.08, –0.24/–0.28,–0.40/–0.42,–o.49/– O.50,–0.61/–0.63,–0.91/–0.92,–01.14/–1.16,1.34/–1.34–1.40/–1.44 V vs. SCE in DCP/DPP mode. Indicating the presence of Ag(I),Cu(II),Pb(II), Cd(II), Sn(II) Ni(II), Zn(II), Fe(III), and Cr(III) in ores samples. Finally the obtained polarography analysis results on galena ore sample and their comparison with atomic absorption spectroscopy Method.
