荧光络合物显色反应中的有机溶剂化效应--镓(Ⅲ)-桑色素-含氧有机溶剂体系

Solvation Effects on Colour Reactions of Fluorescent Complex--Gallium(Ⅲ)-Morin-Aqueous Solvents System

目前,荧光法测定镓常用的试剂有3,5,7,4'-四羟基荧光酮、己基-Lumo(PGME),但镓与Morin的荧光反应的有机溶剂化效应的研究尚未见报道,我们发现在Ga(Ⅲ)-Morin的荧光显色反应中。

Solvation effects of aqueous organic solvents on complexes of Gallium(Ⅲ)-Morin have been investigated by us firstly.It has been proved that in the presence of organic solvents,the sensitivity and selectivity of fluorescent reaction are greatly increased.The fluorescent yield of the solvated complex Ga(Ⅲ)-Morin-MeOH is 0.505.Ahighly sensitive method for the determination of trace Gallium was recommended.The interference of foreign ions was studied.Satisfactory results were obtained in the determination of trace Gallium in pure Berillium and pure Indium.The composition,fluorescent yield,molar absorptivity were measured.
