应用微分脉冲伏安法对口恶霉灵在玻碳电极上的伏安行为及其应用进行了研究 .在pH =7.0的醋酸铵底液中 ,对其进行循环伏安扫描 ,发现于 +1 .0 7V(νs.SCE)产生一氧化峰可用于口恶霉灵的定量测定 .该氧化峰的微分脉冲伏安峰电流与口恶霉灵的浓度在 1 .0× 1 0 - 6～2 .0× 1 0 - 3 mol/L范围内呈良好的线性关系 .实验结果表明 ,口恶霉灵在玻碳电极上有明显的吸附性质 The voltammetric behavior of hymexazol on glassy carbon electrode was investigated by differential pulse voltammetry and its application was investigated by cyclic voltammetry in ammonium acetate at pH 7.0, and found to be +1. 0 7V (νs.sCE) to produce a monoxide peak can be used for the quantitative determination of hymexam.It has a differential pulse voltammetric peak current of the oxidation peak and hyponylamine at a concentration of 1.0 × 10 -6 ~ 2. 0 × 10 3 mol / L. The experimental results show that hymexamycin has obvious adsorption properties on the glassy carbon electrode
