在荧光法测定铝的工作中,已应用了很多荧光试剂,但应用表面活性剂的体系还不多。我们在研究阳离子表面活性剂存在下,镉与铁试剂的荧光反应时,发现铝也有类似的反应,在此基础上我们详细地研究了反应条件,比较了不同表面活性剂的增敏作用,用相对法测定了二元和三元络合物的量子效率(φ中),并对其机理进行了初步探讨;本文还研究了共存物质的影响及掩 In the determination of aluminum by fluorescence method, a lot of fluorescent reagents have been used, but there are not many systems using surfactants. When we studied the fluorescence reaction between cadmium and iron reagent in the presence of cationic surfactant, we found that aluminum has a similar reaction. On this basis, we studied the reaction conditions in detail and compared the sensitization effect of different surfactants with The relative efficiency method was used to determine the quantum efficiency (φ) of binary and ternary complexes, and its mechanism was discussed. The influence of coexisting substances
