Determination of mercury in cosmetics on electropolymerized film-modified electrodes

Abstract

Electropolymerized film-electrodes modified with a film consisting of N-ethyl-N-(p-hydroxyphenethyl) amine, tyramine and tri-n-octylphosphine oxide, in a 0.5% Nafion or 0.02% poly(vinyl chloride) matrix were used for an anodic stripping determination of mercury in cosmetics. The most important parameters include thickness of the modifying film, the modifier-to-matrix ratio in the modifying film and the base electrolyte composition. These parameters were investigated in this study. Comparison with results obtained from atomic absorption spectrophotometric analysis (AAS) showed good agreement.
