| Description |
The adsorption effect of the benzyl alcohol (BA) and thiourea (TU) on the electrodeposition of
cadmium from an acid sulphate bath has been studied by electrochemical impedance
spectroscopy (EIS). Maximum adsorption of additive was obtained in BA containing medium.
Results show that the adsorption increases when the concentration of the additives is increased.
The surface adsorption of the additives has lead to a decrease in the double layer capacitance
and to an increase in polarisation resistance. The adsorption process is a spontaneous one and
follows the Langmuir adsorption isotherm model. From the impedance analysis, it is observed that
Cd–TU complexes inhibit the hexagonal like morphology revealed by SEM
