Abstract: Anew fluorescence system of Eu-DPN-NH3-Triton X-100 is investigated in this paper. The optimum conditions to form the system are as follows: concentration of DPN is equal to 5. 0×10-6 mol/L, Triton X-1000. 01% and pH = 9. 0. The fluorescence intensity is a linear function of the concentration of europium at the range of 1. 0× 10-8-8.0× 10-7 mol/L. The method can be used for spectrofluorimetric determination of Eu3+ in a aqueous solution and the detection limit is 6. 0× 10-11 mol/L (9. 1× 10-3 ng/mL). Several samples were analyzed with satisfactory results.
