| Abstract: | Fluorescent properties were investigated by mixing the four chelants with Eu3+ and Tb3+ ions in aqueous solution respectively.The fluorescent intensity varies with chelants,pH value and concentration of chelantes.The chelants can enhance Tb3+ ion luminescence in aqueous solution,especially DTPA-pAS and EDTA-pAS.The sequence is EDTA-pAS>DTPA-pAS>DTPA-pAB>EDTA-pAB.But the chelants can not enhance Eu3+ ion luminescence in aqueous solution.As pH value located in the rang 6.0～12.0,the fluorescent intensity shows only small fluctuation.The fluorescence of Tb3+ ion can be detected even at the concentration of 1.0×10-7 mol/L. |
