聚L-谷氨酸修饰电极的制备及其对扑热息痛的测定
Preparation of Poly(L-Glutamic Acid)Modified Electrode and Its Analytical Application of Paracetamol
摘要
Abstract
The poly ( L-glutamic acid ) modified electrode was prepared. The voltammetric behavior of paracetamol at the prepared electrode was studied. In pH 7. 0 phosphate buffer solution, the concentration of paracetamol showed good linear relationships with the oxidation peak current in the range of 0. 1 ～ 140 μmol/L with the correlation coefficients of 0.998. The limit of detection was 0.03 μmol/L (RSN =3). The developed method was used to determine paracetamol tablet samples with recoveries of 95.2% ～ 104. 8% .关键词
