氨基C酸偶氮氯膦曾用于稀土胶溶络合物体系。该显色剂在醋酸介质中与各稀土元素及钪形成稳定的络合物。这两种络合物的吸收光谱有明显的差异,利用这些差异,我们应用双波长分光光度法直接分别测定了稀土和钪在其混合物中的含量。方法简便、快速。
Amino acid C acid chlorophosphonazo was used for rare earth peptized complex system. The developer forms a stable complex with the rare earth elements and scandium in an acetic acid medium. The absorption spectra of the two complexes are significantly different, using these differences, we use the dual-wavelength spectrophotometric determination of the rare earth and scandium in the mixture content. The method is simple and fast.
