Abstract:

Biochar derived from Eucalyptus (Eucalyptus globulus) wood particles was utilized as an adsorbent to remove Malachite Green (MG) dye from an aqueous solution by varying the different physicochemical parameters. The adsorbent was characterized using FTIR analysis, SEM and XRD. The kinetics of the dye adsorption was analysed using pseudo-first-order and second-order model.The rate of sorption was described as a function of different experimental parameters and was modeled applying Box-Behnken Design (BBD). The results indicate that the response of MGadsorption was appreciably affected by the quadratic terms of contact time, dye concentration, temperature, pH, and adsorbent dose. The statistical analysis was carried out using ANOVA which shows a convincing relationship among the parameters under study.
