分别將電極修飾劑N—乙基一N-（對羥 基苯乙基）胺、對羥基苯乙基胺和三正辛基氧 化膦，以0.5%Nafion或0,02%聚氯乙烯為基 質，電合成薄膜修飾電極當工作電極。以陽極剥除伏安法測定化妝品中汞的含量，並探討修 飾薄膜的厚度、修飾劑對基質之比值和電解液 組成等重要參數。將分析結果與原子吸光法比 較，發現很一致。

Electropolymerized film-electrodes modified with a film consisting of N-ethyl-N-(phydroxyphenethyl) amine, tyramine and tri-n-octylphosphine oxide, in a 0.5% Nafion or 0.02% poly(vinyl chloride) matrix were nsed 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 stndy. Comparison with results obtained from atomic absorption spectrophotometric analysis (AAS) showed good agreement.
