孔雀石绿检测方法

Determination Methods of Malachite Green

采用显微结晶的方法直观地观察孔雀石绿及孔雀石绿分别与Zn2+、C2O42-混合形成的特殊晶形,建立孔雀石绿简便直观的定性检测方法.结合紫外分光光度法,对孔雀石绿作定性定量的研究.通过对比孔雀石绿、Zn2+、C2O42-和孔雀石绿与Zn2+、C2O42-混合物的光谱扫描图,分析孔雀石绿与Zn2+、C2O42-生成的新物质,印证了孔雀石绿的存在.

In order to directly observe special crystal of Malachite Green and mixture of Malachite Green and Zn^2＋,C2O4^2- , microscope and crystal analysis is applied to set up a simple and direct qualitative determination method to Conduct qualitative study on Malachite Green. In view of Malachite Green, Ultraviolet Spectrophotometry is an effective qualitative and quantitative method. With the contrast of scanning spectrogram of Malachite Green, Zn^2＋,C2O4^2-, the new reactants resulted from mixture of Malachite Green and Zn^2＋,C2O4^2- are also analyzed to prove the existence of Malachite Green.
