摘　　要：对氯苯基荧光酮在表面活性剂Tween80-CTMAB存在下,与锗( )形成稳定的混配络合物,其显色体系较单一表面活性剂的p-ClPF显色体系具有更高的灵敏度,提高了体系的稳定性和抗干扰能力,可以不经分离直接测定矿渣样品中痕量锗,结果令人满意.In the presence of Tween80 and CTMAB,pClPF react with Ge to form mixed complex, which has higher sensitivity than single surfactant pClPF color systems,its stability and the ability to eliminate interference are improved. The new method can determinate trace Ge in ore directly without separation and the results of determination are satisfactory.
