| 英文摘要 | the photocatalytic (pc) degradation kinetics of sulfosalicylic acid (ssa) at different ph using tio(2) microspheres were elucidated by modeling. the resultant model had special consideration of adsorption and ph, the adsorption isotherms showed that the lc/ms(2)-identified intermediates were weakly adsorbed on the tio(2) microspheres, thus their adsorption was neglected in the modeling. by contrast, the ssa was significantly adsorbed, thus its adsorption retained as an item in the model. consequently, a non-first-order model was obtained. through the modeling, it was elucidated that the reaction rate increased non-linearly with the ssa adsorption equilibrium constant. meanwhile, it was elucidated that a ph increase favored the hydroxyl radical production to accelerate the ssa degradation, while impeded the ssa adsorption to slower it, hence a neutral ph caused the fastest ssa degradation.
