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.
