Sharma等研究的管状石墨电极(TGE)已成功地应用于以伏安法测定各种芳族氨基化合物和酚化合物。对于大多数含有易氧化功能团或环状结构的药物而言,为了确定这些化合物能否适用,必须在此电极上研究一些重要药物的氧化伏安行为。实验和结果试样: 四十种不同药物,其中包括N-取代的吩噻嗪类、磺胺类、嘌呤类、酚类、局部麻醉药和抗生育类化合物(表1)。所有这些化合物在使用前均用标准方法再次纯化。电极装置: 此电极是用纯地蜡浸渍的光谱纯致密石墨棒(Johnson Matthey Chemical Ltd.,Royston,Herts.,England)做成。其装置
The tubular graphite electrodes (TGE) studied by Sharma et al. Have been successfully applied to the voltammetric determination of various aromatic amino compounds and phenolic compounds. For most drugs containing readily oxidizable functional groups or cyclic structures, the voltammetric behavior of some important drugs must be investigated at this electrode in order to determine the suitability of these compounds. Experimental and result samples: Forty different drugs, including N-substituted phenothiazines, sulfonamides, purines, phenols, topical anesthetics and anti-fertility compounds (Table 1). All of these compounds are re-purified by standard methods before use. Electrode Assembly: This electrode was made of purely gravimetric light-dense pure graphite rod (Johnson Matthey Chemical Ltd., Royston, Herts., England). Its device
