In order to assess the interactions between process factors, experiments involving liquid-phase adsorption of cephalexin (CEX) onto silicon-coated iron nanoparticles (Fe 3 O 4 @SIO 2 ) were designed using Box-Behnken Design-Response surface methodology (BBD-RSM). Optimal circumstances used investigate synergistic influence on process’s efficiency. addition, data was test and fit an artificial neural network (ANN) model. Molecular-level DFT calculations CEX molecule carried out. The PW6B95D3/Def2-TZVP level theory build DFT-based descriptors for molecule. At 25°C, pH 5.83, 37.67 min, a dosage 0.8 g Fe 118.01 mg/L CEX, removal efficiency achieved maximum 99.01 percent. For example, we found that OH --- O, NH CH hydrogen bonds, π, π as well dipole-dipole could all be connect nanoparticles. There is strong correlation output target values acquired by BBD-RSM ANN fits. proved excellent tool eliminating CEX.
