Abstract: The kinetic behaviour in the substitution reaction of RE(TCA)2 [TCA=2-(2-arsenophenylazo)-7-(2, 4, 6, -trichlorophenylazo)-1, 8-dihy-droxy-naphthalene-3, 6-disulfonic acid] with CyDTAhas been studied and some kinetic parameters of the reaction system and kinetic equation for determination have been measured and established.Gd and Yin the binary mixture have been determined by using their rate difference in the ligand substitution reaction of RE(TCA)2, with CyDTAat pH3.0. Anumber of synthesized samples are analysed by logarithmic extrapolation method with good sensitivity and high precision, and it is simple and rapid.
