This pharmaceutical residue has been detected in surface water and sewage wastewater treatment plants (WWTP). Moreover, it has negative impacts on human and ecosystems. The main aim of this work is to remdiate water from SMX using two different water treatment techniques i.e. adsorption and photo-catalytic degradation by using silver phosphate. The materials were characterized using structural (e.g. EDX, FTIR and XRD), and morphological such as BET, and SEM analytical methods. The percentage of elimination of SMX at optimum solution pH, adsorbent dose, initial drug concentration and equilibrium time, was 95.15% by adsorption which corresponds to a maximum adsorption capacity (Q max ) of 1299.7 mg g − 1 and the removal percentage of SMX was 98.2% according to the photocatalytic degradation with Q max = 994.7 mg g − 1 . Langmuir-Freundlich isotherms model is the best to describe the photo-degradation of SMX onto silver phosphate and Fritz Schlunder model is the best to describe the adsorption of SMX onto silver phosphate .
