Abstract
The thesis deals with the study of the effect of the SAS on the
electrodeposition process in acidified CUS04 solution and includes
three chapters
The first chapter presents a survey on the mass transfer
processes, types and shapes of electrodes, and literatures survey on
previous work.
The second chapter is devoted for the results change of volt
with current obtained by above measurements in absence and in
presence of SAS with different concentrations and at different
temperatures for cell using copper and lead anodes. The limiting
’j f.. I--
currents, 11, and the thermodynamic parameters (L1E, L1G, L1H, L1S)
were calculated.
The third chapter also discusses these results. It was found
that Langrnuir isotherm was applied and the adsorption parameters
were calculated which were found to obey Langmuir adsorption
isotherm. Data showed that the addition of SAS decrease the
limiting current, and the decrease in limiting current is ranged from
5.7% to 26% for cell using copper anode.and from 11.11 % to 50%
in the case of cell using lead anode depending on the nature of SAS
and its concentration and alcohol. It is suggested that the decrease in
the limiting current is attributed to adsorption of acid on the copper.
