The fluorescence kinetic characteristics of binary complex Ti-3,5-dibromosalicylfluorone (Ti-3,5-DBSAF) was studied by stopped-flow fluorescence kinetic method, the results show that its rate equation is R=k•[Ti4+]•[H4R]•[H3+ O]-1, refering to Eigen-Tamm mechanism, the reasonable mechanism is derivated. The possibile geometric structure of the binary complex was also discussed.
