Nickel phthalocyanine tetrasulfonate anion (NiPcTS^-^4) in aqueous solution could enter the film of cationic surfactant didodecyldimethylammonium bromide (DDAB) by ion exchange and form NiPcTS^-^4-DDAB film electrode. Cyclic voltammetric experiments showed that, in KBr solution, the film electrode had a pair of well-defined reduction and oxidation peaks. The cathodic and anodic peak potentials were-0.83V and -0.74V(vs.SCE), respectively. The electrochemical parameters, such as charge transport diffusion coefficient, Dct, and heterogeneous electrode reaction rate constant, k°', were determined. The NiPcTS^-^4-DDAB film electrode could be used to catalyze electrochemical reduction of various halogenated acetic acids. Apparent catalytic reduction rate constants of these systems were also estimated.
