【Abstract】 The structures of compounds formed from acidic light yellow G with rare earth ions were characterized by elemental analysis, IR, NMR and TGA. The experimental showed the complexation occurred at the position of sulphonic acid group other than azo and hydroxyl group of acidic light yellow G and the fluorescence of compound of acidic light yellow G and cerium ion was as well observed at Amax 528nm in alcohol solution for the first time.更多还原
