Abstract

The search for the development of non-cyanide zinc plating baths resulted in identification of nC\vcr complexing ligands, The deposition and dissolution of zinc was studied by cyclic voltammetric studies using a bath composition consisted 01' D, 12M Zinc oxide, 2,75M sodium hydroxide and required quantity of triethanolamine and furfuraldehyde Classy carbon (C 1, Platinum and SCE were used as working electrode, counter electrode and reference electrode respectively, The studies were made at different concentrations or the above additives at variuus scan rates at 30Q C. The pH of the bath was maintained at 11.5 to 120, The deposition of zinc from zincale solutions undergoes successive reduction tv Line, The chemical step followed by first electron transfer is the slow step. Trietlnnulamine and furfuraldehyde were found to participate in the electron transfer process. Detailed mechanism or deposition and dissolution in presence of triethanolamine and furfuraldehyde are discussed.
