Abstract: In the present paper, the absorption spectra in the CAS, Sc-CASand Sc-CAS-CTMABsystems were measured. According to equiabsorbance diagram the composition ratio;bf the ternary complex is Sc:CAS:CTMAB=1:2:2. By kinetics method the obtained results show that its rate equation is R=k[Sc(h)][CAS][CTMAB]-2. Referring to Eigen-Tamm mechanism a micelle-solvent cage mechanism is suggested. After the mechanism being treated by the equilibrium concentration method the rate equation is consistent with experimental results. The geometrical configuration of the ternary complex and reaction mode are also discussed.
