In response to the increasingly severe antibiotic pollution in water bodies, this study developed a new type of magnetic nano cobalt @ zero valent iron that is easy prepare and inexpensive( nCo@nZVI ) Composite materials. The sheet-like nZVI was prepared using rheological phase inversion method, followed by synthesis through liquid-phase reduction. material's physical chemical properties, along with its structure, were meticulously characterized utilization various techniques, including BET, FESEM, XRD, HRTEM, EDS, XPS, FTIR. Batch experiments conducted evaluate adsorption-degradation mechanism TC material Fenton system, investigate effects factors such as temperature, pH value, initial ion concentration on removal efficiency. results indicated under conditions 7 temperature 20°C, could reduce wastewater from an 20mg/L trace levels within 120 minutes. Adsorption kinetics isotherm analysis revealed adsorption process pseudo-second-order kinetic model Langmuir model, indicating predominantly capacity 25.33mg/g. Thermodynamic studies have shown occurs spontaneously. Furthermore, composite environmentally friendly cost-effective. It has advantages being recyclable reusable external fields, showing great potential remediation contaminated sites, method guiding significance for recovery containing wastewater.
