【摘要】 本文以表面直径3mm的蜡浸石墨碳为工作电极,在0.3mol/L NH₃·H₂O-NH₄Cl基底溶液中,用单扫描示波极谱仪制作VB₆的阳极化二阶导数极谱曲线,其峰电位Ep为+0.65V（vs SCE）。在1～70μg/ml范围内,峰幅高ip与浓度间呈线性关系。方法应用于药剂分析中,误差在±5％以内。更多还原

【Abstract】 A single sweep oscilloscopic polarographic method with the wax-impregnated graphite as a working electrode for the determination of VB₆ is studied. The peak potential of second order derivative anodization voltammetric curve in 0.3 mol/L NH₃·H₂O-NH₄CI base solution was +0.65 V （vs. SCE）, the peak height was linearly related to the concentration in the range of 1～70μg/ml. The method was applied to the pharmaceutical analysis with relative error of ±5％.更多还原
