邻菲咯啉及其与Pd(Ⅱ)、Os(Ⅳ)、Au(Ⅲ)、Sn(Ⅱ)、Fe(Ⅱ)、Ga(Ⅲ)、Th(Ⅳ)配合物的吸附伏安特性
THE VOLTAMMETRIC CHARACTERISTICS OF THE ADSORBED 1,10—PHENANTHROLINE AND ITS COMPLEXES WITH Pd(Ⅱ),Os(Ⅳ),Au(Ⅲ),Sn(Ⅱ),Fe(Ⅱ),Ga(Ⅲ)AND Th(Ⅳ)
【摘要】 本文研究了邻菲咯啉在Na2SO4、KCl、KNO3溶液中的直流取样极谱,常规脉冲极谱行为及其循环伏安特性。邻菲咯啉在滴汞电极上的还原产生两个波,第一个波是吸附前波,第二个波是二电子不可逆还原。紫外光谱吸收说明在上述溶液中邻菲咯啉与 Pd(Ⅱ)、Os(Ⅳ)、Au(Ⅲ)、Sn(Ⅱ)、Fe(Ⅱ)、Ga(Ⅲ)、Th(Ⅳ)均能形成配合物,用直流取样极谱及循环伏安法研究了这些配合物的伏安特性,发现它们均能在汞电极上产生具有吸附性的还原波。
【Abstract】 The polarographic and voltammetric behaviour of the 1,10-phenan- throline(o-Phen)in Na2SO4,KCl and KNO3 was investigated.The two waves were observed for reduction of o-Phen.The first one was a pre- wave and the second one resulted from the irreversible reduction of o-Phen.The experimental results by spectrophotometry showed that complexes of Pd(Ⅱ),Os(Ⅳ),Au(Ⅲ),Sn(Ⅱ),Fe(Ⅱ),Ga(Ⅲ)and Th(Ⅳ) with o-Phen existed in three solution.The complexes could be adsorbed and reduced at the mercury electrode.
