In the present work, the photocatalytic degradation of clofibric acid (CA) and tetracycline (TC) was studied using an annullar, packed-bed reactor filled with TiO2-coated glass rings, irradiated internally and externally by UV LEDs. The performance of single pollutants solutions and binary mixtures under different irradiation conditions was evaluated. The quantum efficiency parameter was also estimated. It was found that the presence of TC significantly decreased the degradation of CA, whereas CA did not affect TC degradation. Illumination with total LEDs provided higher photon absorption rates and reaction rates than illumination with only external LEDs but the quantum efficiency of each compound was practically not affected by the irradiation condition.
