在Cu(Ⅱ)的存在下,Al(Ⅲ)-PAN[1-(2-吡啶偶氮)-2-萘酚]络合体系的荧光强度下降。铜量在10-8~ 10-6M范围内,荧光强度的变化值与其含量成正比。
In the presence of Cu (Ⅱ), the fluorescence intensity of Al (Ⅲ) -PAN [1- (2-pyridylazo) -2-naphthol] complex decreased. The amount of copper in the range of 10-8 ~ 10-6M, the fluorescence intensity changes with its content is proportional to.
