摘要
本文研究了一阶导数高速脉冲极谱祛,并将其运用于氯化钠及其制剂的定量分析中。在-0.11V(vs Ag/AgCl)处出现一良好的导数极谱峰,在6.2×10^(-4)～3.1×10^(-3)mol/L范围内,浓度与导数峰电流呈线性关系。检测限为3.1×10^(-7)mol/L。操作简便、快速、灵敏,结果准确。
The first Derivat-
ive High-speed pulse polaro-graphy was
studied. It was used for the Quantitative
Analsis of Natrii Chloridi and its prepa-
ration. It was found that a well derivat-
ive peak was obtained in aqueous soluti-
on at -O. 11 (rs Ag/AgCl). An excellent
linear relationship was obtained between
the concentration (6.2×10^(-4)～3.1×10^(-3)
mol/L) and derivative peak current. The
detection limit of this method for 3.0×
10^(-8)mol/L. The manipulation is simple,
swift, and sensitive. Its resultis very
accurate.
