摘要

合成容易脱水的对甲苯磺酸镉,首次用于有机溶剂中的电化学研究.Cd( )在Cd(p-CH3C6H4SO3)2+TBAP+DMSO中Pt电极上还原时,首先出现镉的欠电位沉积,然后电沉积镉.4-甲基-7-羟基香豆素、3-氨基香豆素与镉离子配位,使镉离子的还原电位向负方移动.

Abstract

Cadmium p_toluenesulfonate was synthesized and tested electrochemically for the first time. This salt can lose all the hydrated water easily and the dehydrated salt do not deliquesce in the air.Hence,the cadmium p_toluenesulfonate is suitable for the electrochemical studies in organic solvents.When the Cd(Ⅱ) reduced on Pt electrode in Cd(pCH3C6H4SO3)2+TBAP+DMSO, underpotential deposition of cadmium occurred at first, and then cadmium deposited. 4_Methyl_7_hydroxylcoumarin and 3_aminocoumarin coordinate with Cd(Ⅱ) respectively, as a result the reductive potentials of Cd(Ⅱ) moved to the negative direction.
