Abstract
Silver is used as a deposit for decorative and aesthetic appeal on jewellery, hollowers, flatware etc. It is
also used in engineering industries for various reasons like high heat and electrical conductivity and good
antigalling property on bearings, electronic components like socket contacts, ~lip rings, switch gear and
wave guides for radars etc. Usually, silver is electroplated from cyanide based electrolytes and these
solutions contain higher concentrations of both silver and cyanide causing heavy pollution due to emuents.
Also. silver being costly, it was considered worthwhile to investigate the feasibility of evolving a bath
formula with low concentration of silver as well as cyanide with equivalent characteristic features to the
concentrated baths. Experiments were carried out with different concentrations of silver and cyanide and
the results are compared with that of conventional cyanide based baths.
