Feasibility of high silica ZSM-5 recovery by ozone with sulfamethoxazole removal from water

Original language description

This work assessed the feasibility of recovering exhausted high-silica ZSM-5 for the first time. High-silica ZSM-5 (HSZSM-5) loaded with sulfamethoxazole (SMX) was regenerated by water-dissolved ozone. Results showed that 97% recovery of adsorption capacity of regenerated HSZSM-5 was obtained at 2,54 mg/L of ozone after 15 min reaction. Lower SiO2/Al2O3 ratio of HSZSM-5 and initial SMX concentration had a higher recovery ratio of adsorption capacity of regenerated HSZSM-5. The sequential HSZSM-5 adsorption (AD) and ozone oxidation (OZ) experiments were also performed to investigate the effect of pH on the regeneration efficiency of loaded HSZSM-5 and the regeneration mechanism was characterized by fourier-transform infrared spectroscopy, X-ray diffraction and thermogravimetric analysis. No degraded isoxazole ring of SMX adsorbed in the sinusoidal channels of HSZSM-5 was responsible for the decreased recyclability of HSZSM-5.Higher ozone activity of deprotonated SMX at higher pH (above pKa2) favored t
