研究了用单扫描示波极谱法测定甲孕酮的条件和方法.在0.4mol/LB·R—乙醇混合溶液介质中,甲孕酮在-1.43V(vs·SEC)有一敏锐的单扫描示波极谱峰,峰高与甲孕酮浓度在4.0×10-6~5.2×10-3mol/L范围内呈良好的线性关系,以该极谱峰为基础建立了甲孕酮的单扫描示波极谱测定方法,研究了极谱电流性质,循环伏安法证明电极反应不可逆,电毛细管曲线表明甲孕酮在电极表面有较强的吸附.
The conditions and methods for the determination of MPP by single-sweep oscillopolarography were studied. Medroxyprogesterone diphosphate had a sharp single-sweep oscillopolarographic polar peak at -1.43 V (vs · SEC) in a 0.4 mol / L · R-ethanol mixed medium with a peak height and a concentration of medroxyprogesterone acetate of 4.0 × 10-6 ~ 5.2 × 10-3mol / L showed a good linear relationship. Based on this polarographic peak, a single-scan oscillopolarographic determination of megestrol was established. The polarographic current properties , Cyclic voltammetry proved that the electrode reaction is irreversible, capillary curve shows that medroxyprogesterone has a strong adsorption on the electrode surface.
