Metal Organic Frameworks (MOFs), a new class of porous 3d material, are being researched for their applications in environmental remediation and wastewater treatment. MIL-88-A, an iron-based MOF (Fe<sup>3+</sup>/Fumaric acid), can be synthesized in aqueous medium, a greener advantage over other MOFs. The aim of the project is to synthesize MIL-88-A and test its capability to act as an assisting agent for the elimination of PPCPs from wastewater using AOPs. Sulfamethoxazole (SMX), an anti-inflammatory, was selected as a probe and degraded in chemically activated persulfate (PS) system using MIL-88-A. The study investigated the efficiency of UVA or solar /MIL-88-A/PS systems including the effect of various factors such as MOF load, and UV-A/solar irradiation. It also investigated the activation mechanism, system effectiveness and recyclability of MIL-88-A. Total degradation of SMX occurred in a period of two hours in UVA/MIL-88-A/PS system compared to 5-20 min in Solar/MIL-88-A/PS system.
