| Abstract: | 研究維生素B群在玻璃碳與電沉積汞電極之電化學行為；包括Britton-Robinson (pH 4.86 - 10.03)、磷酸(pH 2.12 and 6.06)、醋酸等緩衝溶液及不同支持電解質等對電化學行為之影響。探討各種因素如沉積材料、時間與汞濃度對汞膜金屬結構電極之特性影響。比較玻璃碳電極與電沉積汞電極之偵測極限，同時測定市售具有抗老化及增白效果之化妝品或養髮製品維生素B群之含量。
The electrochemical behaviors of vitamin B groups on glassy carbon, and electrodeposited mercury electrodes were investigated in a Britton-Robinson buffer (pH 4.86 - 10.03), phosphate buffer (pH 2.12 and 6.06), acetate buffer and an aqueous medium containing supporting electrolyte. The various factors, such as deposition material, time, and concentration of mercury on the precision of the analysis have been explored. A comparision in made between the detection limit of glassy carbon, thin-film modified on glassy carbon and gold electrodes. The electroreduction process is applied for the quantitative determination of vitamin B groups in commercial cosmetic products. |
