摘要
研究了一阶导数高速脉冲极谱法,并运用于盐酸普鲁卡因及其注射制剂的定量分析。在-0.04 V(对 Ag/AgCl)处出现的良好导数峰,于1.0～6.0×10^(-4)mol/L 范围内,导数峰电流与浓度呈线性关系。检测限为3.0×10^(-8)mol/L。操作简便、快速、灵敏,结果准确。
The first derivative high-speed pulse polarography was used forthe quantitative analysis of procaine hydrochloride and its injection.In aqueoussolution at-0.04V(vs Ag/AgCl),an excellent linear relationship was obtained bet-ween the concentration 1.0～6.0×(10^(-4)mol/L)and the derivative peak current.The detection limit was 3.0×10^(-3)mol/L.The manipulation is simple,rapid,sen-sitive,and very accurate.
