摘要
本文研究了十二钨酸络钴酸钾(K_5Co(Ⅲ)W_(12)O_(40),简记为Co(Ⅲ)WO)氧化电位和pH的关系,Co(Ⅲ)WO在最大吸收处(388nm)吸光度和浓度间的关系。用分光光度法研究了Co(Ⅲ)WO在HAc-NaAc缓冲体系中氧化硫酸肼、不对称盐酸二甲肼、硫酸羟胺的动力学,给出了相应的表观活化能、活化熵等动力学参数,讨论了通过氩键传递电子的可能性。
The oxidation of dimethylhydrazine hydrazine and hydroxylamine by 12-tungsto-balt (III) ate in acetate buffer solution were investigaied.In the pH range of the experiment,all the systems have a similar empirical rate equation:The values of the activation parameters of the reactions were given.A mechanism of electron transfer through hydrogen bonding was suggested.
