Standardization of reagents is not required in coulometric analysis as the quantity of reagent prepared is directly determined from the charge passing through the cell.
Somogyi, "Coulometric analysis as a precision method," Analytical Chemistry, vol.
In case of the polarographic or coulometric analysis
it is either the anodic oxidation or cathodic reduction of phenols [22-24] which is employed for the qualitative or/and quantitative analysis of phenols in environmental, industrial or food samples.
Coulometric Analysis: A technique in which the amount of a substance is determined quantitatively by measuring the total amount of electricity required to deplete a solution of the substance.
