An electrode composed of an epoxy resin and graphite powder is fast and convenient to fabricate. The performance as a working electrode for cyclic voltammetry measurement of hexacyanoferrate(III) in aqueous and nonaqueous systems is compared with a paraffin carbon paste electrode. Well defined current-potential curves, and well linearity of current-root scan rate and current-concentration system are reported. The electroanalytical studies of the octyl methoxycinnamate, oxybenzone, benzophenone, octyl salicylate, and butyl methoxy dizenzoyl methane, that are often used as sunscreens in commercial cosmetic products, were described at the carbon-epoxy composite electrodes in nonaqueous solvent.
