The issue of antibiotic residue causing environmental contamination must be addressed with urgency and seriousness. The present study used a heterogeneous Fenton-subcritical water process to degrade synthetic liquid waste containing a mixture of tetracycline and erythromycin. MIL-88B(Fe) was utilized as a catalyst, produced using the solvothermal method at 150 °C. Utilizing SEM, XRD, and nitrogen sorption, the catalyst was characterized. In addition, the degradation capability of heterogeneous Fenton subcritical water was compared to that of the conventional Fenton process, subcritical water, and homogeneous Fenton-subcritical water processes. The experiment results demonstrated that the heterogeneous Fenton-subcritical water process was preferable to other methods for degrading tetracycline and erythromycin. This study found that tetracycline degraded at a maximum rate of 91.3% and erythromycin at 77.7%. MIL-88B(Fe) experiments were also conducted to determine the catalysts' efficacy. © 2024 The Authors
