作者用半微分阴极吸附伏安法测定地高辛的方法，在1．0×10－3mol／LNaOH底液中，于—1．0V富集2min，以100mV／s向阴极扫描，有一稳定的还原峰。在地高辛浓度为4．0×10－7mol／L～10．0×10－7mol／L范围内，该还原峰峰高与地高辛浓度成线性，检出下限为1．0×10－8mol／L。本文用不同的电化学方法证明，地高辛在悬汞电极上的电极过程为吸附准可逆过程，其饱和吸附量为6．51×10－10mol／cm2，转移系数为0．78。 The authors used semi-differential cathodic adsorption voltammetry determination of digoxin method, in 1.0 × 10-3mol / LNaOH bottom solution, enrichment of -1.0V 2min, 100mV / s to the cathode scan, there is a stable Restore peak. In the range of 4.0 × 10-7mol / L to 10.0 × 10-7mol / L, the reduction peak height was linear with the concentration of digoxin, and the detection limit was 1.0 × 10 -8mol / L. In this paper, different electrochemical methods have been used to prove that the electrode process of digoxigenin the mercury electrode is a quasi-reversible adsorption process with a saturated adsorption capacity of 6.51 × 10-10mol / cm2 and a transfer coefficient of 0.78.
