【摘要】 本文提出了稀土—间硝基偶氮氯膦,稀土-间硝基偶氮氯膦-二苯胍的两个极谱络合吸附波体系,并用库仑分析,对照实验和循环伏安等方法研究了间硝基偶氮氯膦的电化学行为,解释了单扫极谱上各个波峰的电极过程。稀土与间硝基偶氮氯膦的络合部位在分子的氯膦一侧。络合物中氯膦一侧偶氮基酶还原形成了络合吸附峰。更多还原

【Abstract】 In this paper,two adsorptive complex waves are presented,the rare earth elements -Chlorophosphonazo-m-NO2 system, and the rare earth elements-Chlorophosphonazo-m-NO2-Diphenlguanidine system. The mechanism of electrode reduction of Chloropho-sphonazo-m-NO2 was investigated by controlled potential coulometry, cyclic voltamm-etry and reference waves of Chlorophosphonazo-m-Acet, Chlorophosphonazo I and m-nitroaniline. The peaks exhibited in single sweep polarography by Chlorophosphonazo-m-NO2 have been elucidated. It is shown that the complexation takes place at the chlorophosphonazo site of the molecule, and the adsorptive complex wave is produced by the reduction of the chlorophosphonazo in the complex compound.更多还原
