| 摘 要： | 研究了10个体系约100种不同条件下茜素紫的极谱行为，在不同体系、不同条件下，茜素紫表现出来的极谱峰数目不同。在较高酸度下，一般表现为一个一阶导数波，峰电位较正；在较低酸度下，一般表现为多个一阶导数波，峰电位较负。极谱峰是茜素紫在汞电极上吸附还原产生的，而且峰电流与茜素紫的浓度在一定范围内成线性关系。

| Abstract: | Alizarin violet polarographic behaviors at about 100 conditions of 10buffer systems were studied. Alizarin violet has distinct numbers of polarographic peak at distinct conditions. At higher acidity condition it has a differentialpeak with lhe peak potential was positive;at lower acidity condition it has muIti differential peaks with the peak po tentlal were negative. Its adsorption and reduction on mercury electrode produce the polarographic peaks of alizarin vi- oIet. And peak current with concentration of alizarin violet has linearity at a certainty concentration range. |
