The catalysts were characterized using XRD, SEM-EDS, VSM, UV-DRS, and pH pzc . The effects of photocatalyst dose (0.25, 0.5, 0.75, and 1.0 g/L), dye concentration (10, 20, 30, and 40 mg/L), and irradiation time (0–210 minutes) were all examined as photocatalytic degradation variables. The results showed that the CoFe 2 O 4 /SiO 2 /Ag composite was superparamagnetic with a saturation magnetization of 41.82 emu/g and had a band gap of 1.82 eV. The highest efficiency of decreasing the concentration of Congo red dye of 93.70% was obtained with an initial concentration of 10 mg/L, a catalyst dose of 0.5 g/L, and an irradiation time of 180 minutes. This study indicated that the composite had antibacterial properties against Gram-positive ( S. aureus ) and Gram-negative ( E. coli ) bacteria with the same MIC value of 1.25%. These results indicated that the CoFe 2 O 4 /SiO 2 /Ag composite has significant potential for applications in wastewater treatment.}, issn = {2597-9914}, pages = {235--244} doi = {10.14710/jksa.25.7.235-244}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/46794} }
