The dry gels of the Ce-Ti mixture with attapulgite（ATP） were synthesized by sol-gel method and then were calcined to obtain Ce0.5Ti0.5O2-ATP composites.In the study of photocatalytic degradation of the antibiotic ciprofloxacin，it was found that the photocatalytic activity of Ce0.5Ti0.5O2-ATP could be significantly improved at 5% of ATP mass.A series of characterisation was carried out to obtain the composite's crystalline phase structure，morphology and surface state information，and to verify the effective recombination between Ce0.5Ti0.5O2 and ATP.The test of the adsorption performance，light absorption intensity and range，and photogenerated carrier recombination rate of the catalysts revealed that the Ce0.5Ti0.5O2-ATP composite could improve the light absorption ability and significantly increase the photogenerated carrier lifetime.It was further verified that the photogenerated holes and hydroxyl radicals were the main factors in the photocatalytic degradation of ciprofloxacin in combination with free radical capture experiments.On the basis of the total organic carbon test，a possible reaction mechanism for the photocatalytic degradation of ciprofloxacin by Ce0.5Ti0.5O2-ATP composites was proposed.
