摘要
采用差分脉冲伏安法测定多潘立酮的含量。该方法是在pH为2.3的briton - robinson缓冲溶液中，用+0.64 V vs. SCE在玻碳电极上阳极氧化多潘立酮。用循环伏安法测定了氧化的可逆性;电极过程不可逆，扩散吸附可控。在多潘立酮浓度1.0 × 10 - 6 ~ 2.0 × 10-5 μ M范围内均呈线性，检出限为4.0 × 10-7 μ M。该方法在不受辅料干扰的情况下，可用于片剂型多潘立酮的测定。
“Determination of domperidone in tablet dosage form by anodic differential pulse voltammetry”
A differential pulse voltammetric method was described for the determination of domperidone. The method was based on the anodic oxidation of domperidone on a glassy carbon electrode at +0.64 V vs. SCE in Britton–Robinson buffer solution of pH 2.3. The reversibility of the oxidation was tested by cyclic voltammetry; the electrode process is irreversible and diffusion–adsorption controlled. Calibrations are linear over the range 1.0 × 10–6–2.0 × 10–5 M of domperidone with a detection limit of 4.0 × 10–7 M. The method was applied, without any interference from the excipients, to the determination of the drug in a tablet dosage form.
