中文摘要：

用伏安法研究了维生素B6(VB6)在碳纤维微电极(CFME)上的电化学行为及其测定。以0.1 mol/L的邻苯二甲酸氢钾(pH 5)的缓冲液为底液,在最佳实验条件下,VB6在0.94 V(vs,SCE)的氧化峰峰电流与VB6在5.0×10-6~8.0×10-4mol/L范围内呈良好的线性关系,检出限为1.0×10-6mol/L(S/N=3)。方法用于药剂中的VB6的分析。

英文摘要：

The electrochemical behavior of pyridoxine at a carbon fibre microelectrode was investigated by voltammetry.In 0.1 mol/L potassium acid phthalate buffer solution(pH 5.0),under the optimized conditions,the pyridoxine exhibited a sensitive oxidation peak at 0.94 V(vs.SCE),the current showed a linear dependence with concentration in the range of 5.0×10-6 ～8.0×10-4 mol/L and the detection limit was 1.0×10-6 mol/L(S/N=3).The proposed method was applied to determination of the concentration of pyridoxine in pharm...
