“…Based on the results of ANOVA, p-value < 0,05 ensures that the second order polynomial model is significant. A non-significant lack-of-fit test (low F-value and P-value > 0.05) indicates that the model is well validated for MB adsorption [19]. Three process parameters (A, B, C) were found to be significant.…”

This study focused on the optimization of methylene blue removal on a magnetic activated carbon from the carbon-rich agro-industrial residue, sugarcane bagasse, synthesized by microwave method. The adsorption process was assisted by ultrasound. The magnetic sugarcane bagasse activated carbon (MSB) was characterized by FTIR and SEM-EDX. Based on FTIR results, the functional groups found in magnetic sugarcane bagasse activated carbon are O-H, C=C, C-O, and Fe-O. The SEM results show that MSB is porous with a rough surface. In addition, EDX data found the presence of three main elements, namely C, O, and Fe. Response Surface Methodology (RSM) Box-Behnken Design was applied to analyze the effects of three parameters, including adsorbent dosage (50-100 mg/L), ultrasonic power (100-200 W), and contact time (30-60 min). The obtained optimum conditions of the adsorption process were the sonication power of 155.65 W, the adsorbent dosage of 89.77 mg/L, and the sonication time of 57,81 minutes. The results indicated that the parameters of adsorbent dosage, ultrasonic power, and contact time influenced the response (qe and methylene blue removal).

“…However, the preparation process is inherently complex and unsuitable for large-scale production. In a specific study conducted by Li et al , 25 they successfully prepared an Fe 3 O 4 @Zn-MOF composite material through a straightforward process of ultrasonically mixing Fe 3 O 4 MNPs with a Zn-MOF solution. Notably, the magnetic adsorbents obtained using this method demonstrate exceptional reusability, which surpasses five consecutive cycles of reuse.…”
