本文详细研究了对氟苯基荧光酮与铝(Ⅲ)的反应条件,试验了表面活性剂和共存离子的影响。拟定了荧光熄灭法测量微量铝的方法。本方法用于直接测量水中的微量铝。结果较好。 In this paper, the reaction conditions of p-fluorophenylfluorone and aluminum (Ⅲ) were studied in detail, and the influence of surfactants and coexisting ions was tested. A method of fluorescence quenching method for measuring trace aluminum was proposed. This method is used to directly measure trace amounts of aluminum in water. The result is better.
