本文研究了尼克酸在碳糊电极上的伏安行为。在0.15mol/L HCl溶液中,尼克酸在-1.25V处产生一灵敏阴极溶出峰,在1.0×10~(-5)～2.0×10~(-4)mol/L范围内,波高与浓度呈良好线性关系,检测下限为3.3×10~(-6)mol/L。
In this paper, the voltammetric behavior of niacin at a carbon paste electrode was investigated. In 0.15mol / L HCl solution, niacin produced a sensitive cathodic dissolution peak at -1.25V. The wave height and concentration in the range of 1.0 × 10 -5 ~ 2.0 × 10 -4 mol / L, Showed a good linear relationship with the detection limit of 3.3 × 10 -6 mol / L.
