Natural convection mass transfer in presence of small amounts of alcohols

ABSTRACT

The effect of methanol, ethanol, n-propanol and isopropanol on the rate of cathodic deposition of copper from acidified copper sulfate solution was studied. These alcohols caused a decrease in the limiting current by an amount ranging from 5.95 to 35.55%, depending on the type of alcohol and concentration. Langmuir adsorption isotherm was applied. The values of heat absorption and free energy of adsorption were calculated
