摘要
研究了2,6-二甲基苯酚在玻碳电极上的电化学行为。通过线性扫描伏安法研究了支持电解质、溶液pH和扫描速度对2,6-二甲基苯酚测定的影响。并采用示差脉冲伏安法研究了氧化峰电流与2,6-二甲基苯酚浓度之间的关系,结果显示峰电流与2,6-二甲基苯酚的浓度在7.0×10-5～2.0×10-2 mol/L之间有良好的线性关系。同时玻碳电极对2,6-二甲基苯酚的测定具有较好的重现性和稳定性。
The electrochemical behavior of 2,6-dimethylphenol at the glassy carbon electrode was investigated.The influences of the pH value and scan rate on the electrode reaction of 2,6-dimethylphenol had also been studied by the linear sweep voltammetry.The relationship between the current and concentration of 2,6-dimethylphenol was studied by the differential pulse voltammetry.The results showed the peak current was linearly proportional to the concentration of 2,6-dimethylphenol in the range from 7.0×10^-5 to 2.0×10^-2 mol/L.And the glassy carbon electrode possessed good stability and reproducibility for the electrode reaction of 2,6-dimethylphenol.
