荧光法测定痕量镓,大多采用咕吨类试剂,但常需进行萃取.七十年代,日本学者在用萤光镓(及其烷基衍生物)荧光法测镓、铝等时,添加表面活性剂(记作Sf),增强了体系的荧光强度,建立了胶束增敏荧光光度法.以后,史慧明等对该法作过一系列研究并讨论其反应机理.黄酮类试剂(如桑色素)也是镓的一类荧光试剂,但灵敏度不高,选择性也较差.我们发现,在Ga(Ⅲ)-桑色素二元体系中,加入阴离子表面活性剂(记作a-Sf)十二烷基磷酸钠(记作SLS)之后,方法的灵敏度比相应的二元 Fluorescence method for the determination of trace amounts of gallium, most commonly used xanthene reagent, but often need to extract the seventies, Japanese scholars in the use of fluorescent gallium (and its alkyl derivatives) fluorescence measurement of gallium, aluminum, etc., the surface Active agent (denoted as Sf) to enhance the fluorescence intensity of the system, the establishment of micellar sensitizing fluorescence spectrophotometry later, Shi Huiming and so on the law made a series of studies and discusses the reaction mechanism of flavonoids (such as mulberry Pigment) is also a type of gallium fluorescence reagent, but the sensitivity is not high, the selectivity is poor.We found that in Ga (Ⅲ) - Morin binary system, adding anionic surfactant (denoted as a-Sf) ten After sodium dialkylphosphate (referred to as SLS), the method is more sensitive than the corresponding binary
