Determination of half-wave potentials of selected chlorophenols

Cyclic voltammetry was used in cetyltrimethylammonium bromide (CTAB) micellar solution to determine the half-wave potentials of selected chlorophenols, CPs. It is observed that all the electrochemical parameters of the studied CPs decrease with an increase in the number of chlorine atom(s) attached to the parent compound. The mathematical relationship between the obtained E_1/2 and the number of chlorine atoms in the parent compound is given. The formal potentials, E^0', of the CPs are approximated from the obtained half-wave potentials.
