What are the factors on which exchange current density of an electrode depends, and how can they be predicted?

While surface roughness is an obvious factor, this is not what is exactly asked. Rather, periodic variation of exchange current density (of an electrode) with solution chemistry (of electrolyte)...

COD, TOC, absorbance and BOD if possible. Only COD won't posses enough critical analysis.

Electrochemical dye activity at the anode can be calculated by means of measuring the current across the anode and then performing a calculation on the intensity

of dye colour both at the anode at the cathode and throughout the solution between

the electrlysis poles.For a clour indicator in most solutions a blue or green clour dye is best as optical photographs of the activity can be taken and compared with different time periods in the reaction pathway.If this is helpful I can supply the

required equations for the polar calculations.Shane.
