The present study utilized chemically modified porous carbon (CMPC) as a robust adsorbent for MB treatment. The characteristic findings revealed the existence of many functional groups (C–O/C = O, C–C/C = C, C–OH, – COOH, C–C = O, etc.) on the surface of the high-defect structure of CMPC. Additionally, influential factors: methylene blue (MB) concentration (116–284 mg/L), CMPC dosage (0.16–1.84 g/L), and pH (3.6–10.4) were assessed by response surface methodology. By applying optimized conditions, the highest MB removal and adsorption capacity were confirmed at 90% and 181.82 mg/g, respectively. Role of surface functional groups in adsorption mechanisms was meticulously explained. [ABSTRACT FROM AUTHOR] |
