水杨基萤光酮(SAF)用作金属离子的光度剂,早有研究。因络合物水溶性和稳定性差,长期来未得到广泛应用。我国的分析工作者近年发现,在长链季铵盐存在下,它能与Ti、Ge、Sn等一些高价金属离子形成三元胶束络合物,灵敏度和选择性都比较高。这就为SAF在光度分析中的应用,开辟了新途径。用SAF和溴化十六烷基三甲铵(CTMAB)测定锗已有报导。 Salicyl fluorone (SAF) as a metal ion photometric agent, has long been studied. Due to the poor water solubility and stability of the complex, it has not been widely used for a long time. In recent years, our analysts have found that in the presence of long-chain quaternary ammonium salt, it can form ternary micelle complexes with some high-valent metal ions such as Ti, Ge, Sn and the like, resulting in high sensitivity and selectivity. This opens up new avenues for the application of SAF in photometric analysis. The determination of germanium with SAF and cetyltrimethylammonium bromide (CTMAB) has been reported.
