摘要
用DY2000恒电位器对不同浓度氯化钴的循环伏安法进行了实验测定。我们使用0.1 M KCl作为支撑电解质。采用玻碳工作电极,在使用前进行提纯和抛光。另外两种电极分别是铂丝和Ag/AgCl电极,电极置于饱和氯化钾溶液中。在298.65 K温度下,用不同浓度的头孢曲松二钠(Ceftriaxone disodium salt, Cefs)研究了CoCl2与Ceftriaxone disodium salt (Cefs)相互作用的络合特性。讨论了络合物的氧化还原机理和稳定常数。对CoCl2与头孢曲松二钠盐(Ceftriaxone disodium salt, Cefs)相互作用的扫描速率和不同动力学参数进行了评价,并对其取值进行了讨论。
Cyclic Voltammetry of Aqueous CoCl2 in the Presence of Ceftriaxone Disodium Salt (Cefs) at 298.65 K
Cyclic Voltammetry of Cobalt chloride with different concentrations was measured experimentally using DY2000 potentiostat. We used 0.1 M KCl as supporting electrolyte. Glassy carbon working electrode was used, purified and polished before use. The other two electrodes are platinum wire and Ag/AgCl electrode put in saturated KCl solution were used. The complex characters for the interaction of CoCl2 with Ceftriaxone disodium salt (Cefs) were studied with the use of different Ceftriaxone disodium salt (Cefs) concentrations at 298.65 K. The oxidation, reduction mechanisms and the stability constants of the complexes formed are discussed. Scan rate and different kinetic parameters resulted from the interaction of CoCl2 with Ceftriaxone disodium salt (Cefs) were also evaluated and their values were discussed.
