本文利用循环伏安法研究了组氨酸钴和碘代组氨酸钴配合物在不同条件下的氧合过程 ,通过与光度法和电位滴定法的研究比较 ,探讨了以循环伏安法研究这两种配合物的氧合过程的可行性 .
The oxygenation of Histidine_Co and Monoiodohistidine_Co complexes were studied by cyclic valtammtry under certain conditions,The possibility of studing the oxygenation processes by cyclic voltammetry method was proposed and discussed in comparison with the results of potentiometry and spectrophotometry.
