钴(Ⅱ)-TAR络合物电化学特性及应用
ELECTROCHEMICAL CHARACTERISTICS OF THE COMPLEX OF CO(Ⅱ) WITH TAR AND ITS ANALYTICAL APPLICATION
【摘要】 在pH 9.0缓冲溶液中,Co(Ⅱ)一TAR络合物在—0.78V呈现—吸附阴极溶出伏安峰。富集时间为 1.0min,Co(Ⅱ)的检测下限为 5.0×10-11mol·L(-1)。用循环伏安法和线性扫描伏安法测得αn。为 1.56。
【Abstract】 In a buffer solution of pH 9.0, the complex of Co (Ⅱ) with TAR gives an adsorptive cathodic stripping voltam-metric peak at -0.78V. This characteristic has been applied to the determination of traces of Co(Ⅱ). The detection limit is 5.0×10-11mol·L-1. By cyclic voltammetry and linear sweep voltammetry anα and have been found to be 1.56.
