Complexation of Eu and Tb with fulvic acids (FA) has been studied by time-resolved laser-induced fluorescence. The lanthanide species are excited by a pulsed Xe/Cl excimer laser and the short-lived luminescence of the fulvic acids is eliminated by time gating. The conditional binding constants (K') and the total metal-binding capacities of the fulvic acids have been determined from the equilibrium titration curves. No significant variations of the log K' values (about 6) have been found in the… CONTINUE READING
