- 中文摘要: The Polarographic reduction of some arylidene derivatives of benzoic hydrazide are investigated at the DME. The polarograms in solutions of pH.ltoreq.8 consist of a single wave corresponding to 4 electrons in acid media and 2 electrons in alkaline ones. The wave splite into two daughter waves in media of pH.gtoreq.10, the more negative wave increases in height at the expense of ihe original one with rise of pH. The reduction waves are essentially difusion controlled with one proton and two electrons in the rate determining step. The electrode reaction is discussed and the important kinetic parameters are determined.
