茜素紫试剂的极谱研究

Study of Alizarin Violet by Polarography and Its Application

本文研究了在ＨＣＩ－邻苯二甲酸氢钾缓冲溶液中，茜素紫的极谱行为和极谱波的性质，茜素紫在－０．５６Ｖ产生良好的极谱波（ｐＨ２．５），用多种电化学手段证明了该波是２电子不可逆还原吸附波，该方法已用于金属离子Ａｕ（Ⅲ）、Ｓｂ（Ⅲ）的测定。

In HCI-potassium biphthalate buffer,the polarographic behavious and polarogrphicwave properties of Alizalin Violet were studied.Gallein,at-0. 56V(vs. SCE),displays a sensitivepolarographic wave(pH2.5).It can be confirmed that electrode reaction refers to 2 electron transfer,the adsorption and irreversibiiity were proved by some electrochemical methods,while the methods todetermination of Au(Ⅲ)and Sb(Ⅲ)were proposed in previous paper。
