镓的离子缔合物萃取光度法是长期以来人们常用的方法,然而操作繁杂。近来,镓的胶束增溶光度法的研究日益增多,灵敏度高,但大多数没用于实际测定。笔者发现,在表面活性剂存在下,4,5-二溴苯基萤光酮(下称Br-PF)不但对高价金属离子具有很高的灵敏度,而且对某些三价金属离子也有灵敏的显色反应。所以本文较系统地研究了Ga-Br-PF-CTMAB体系的新显色反应。结果表明,在pH7.8~8.5范围内形成了摩尔比
Gallium ion association extraction spectrophotometry is a commonly used method for a long time, however, the operation is complicated. Recently, the study of the micellar solubilization photometry of gallium has been increasing with high sensitivity, but most of them are not used in the actual measurement. In the presence of surfactants, the authors found that 4,5-dibromophenylfluorone (Br-PF) is not only highly sensitive to expensive metal ions but also sensitive to some trivalent metal ions Color reaction. Therefore, this paper systematically studied the new color reaction Ga-Br-PF-CTMAB system. The results showed that the molar ratio was formed in the range of pH7.8 ~ 8.5
