Abstract

Titanium dioxide (TiO₂) was applied as photocatalyst to treat the ceftriaxone sodium solution with high pressure mercury lamp and fluorescent dysprosin lamp as ultraviolet and simulated sunlight source respectively.Ultraviolet spectroscopy was used to determine the concentration of reactant during the degredation of ceftriaxone sodium.The effects of light source,photocatalyst dosage,irradiation time,the existence of electron acceptors and other ions on ceftriaxone sodium degradation were investigated in details.The results indicated that after 5 hours,the degradation ratio of ceftriaxone sodium reached to 93.4% and 73.8% by photocatalytic oxidation with UV and simulated sunlight irradiation under the conditions of initial ceftriaxone sodium concentration 500 mg·L^-1 and TiO₂ concentration 2.5 g·L^-1 and 2.0 g·L^-1 separately.The results also showed that the addition of electron acceptors could enhance the photocatalytic efficiency significantly while the presence of some inorganic ions like HCO₃^-,SO₄^2-,Cl^-might lead to the decrease of the photocatalytic efficiency remarkably.
