Machine learning-driven prediction of biochar adsorption capacity for effective removal of Congo red dye

Carbon Research, Год журнала: 2025, Номер 4(1)

Опубликована: Янв. 22, 2025

Abstract Congo red, a widely utilized dye in the textile industry, presents significant threat to living organisms due its carcinogenic properties and non-biodegradable nature. This study proposes data-driven machine-learning approach optimize biochar characteristics environmental conditions maximize adsorption capacity of for removal red dye. Therefore, six machine learning models were trained tested on dataset containing eleven input parameters (related conditions) capacity. The evaluated using performance metrics such as R-squared ( R 2 ), Mean Squared Error (MSE), Root (RMSE). With highest (0.9785) lowest RMSE (0.1357), Random Forest Regression (RF) outperformed other models. DT XGB also performed well, achieving slightly lower values 0.9741 0.9577, respectively. LR model worst, with (0.4575) (0.6821). Moreover, reliability these was validated 10-fold cross-validation method. RF once again best an value 0.9762. Feature analysis revealed that initial concentration relative dosage C 0 specific surface area BET pore volume PV ) are most factors affecting biochar, while carbon content oxygen nitrogen molar ratio [ (O + N)/C ], diameter D had minimal impact. research demonstrates can accurately predict biochar’s contaminant capacity, enhancing wastewater treatment promoting efficient, cost-effective management.

The complex process for treating industrial wastewater frequently necessitates the employment of efficient treatment techniques to eliminate harmful contaminants before discharge, such as congo red (CR) dye. In this study, adsorption methods were utilized CR by employing hydrogel bead composites derived from sodium alginate (SA) and cetyltrimethylammonium bromide (CTAB). Various concentrations CTAB, including 0.1 wt.%, 1 3 denoted SC1, SC2, SC3 respectively, examined. results demonstrated that has higher swelling percentage lowest carboxyl group (COOH). Experiments carried out under different pH levels, concentrations, durations removal CR. maximum capabilities obtained 141.08 mg/g, 144.50 mg/g 153.24 SC2 SC3, respectively. Freundlich pseudo-second-order models demonstrate best fit both isotherm kinetic analysis across all samples, suggesting a multilayer chemisorption mechanism. Reusability studies revealed strong performance, underscoring beads' potent capability
