| Abstract | Crystal violet (CV), a toxic carcinogenic dye commonly used for dyeing and colouring,is difficult to remove from effluents due to its complex structure. Currently, adsorption uti-lizing green adsorbent derived from abundant, low-cost agricultural wastes is an efficient andsimpler technique than other dye removal methods. This study aims to evaluate the potentialof banana pseudo stem (BPS) as biochar and biosorbent feedstock for CV dye removal. Batchexperiments were conducted to investigate the effect of various adsorption parameters withone factor at a time (OFAT) analysis. The adsorbent characterization with the FTIR iden-tified the presence of carboxylic, hydroxyl and amine groups, while SEM images showedrough, irregular pore structures, which resulted in dye molecules' strong adsorption onto theadsorbent surface. Using BPS biosorbent and BPS biochar, the highest CV removal of 91.9%and 93.7% was achieved at the same optimum adsorption conditions? pH 3, 2 g/L adsorbentdosage and 60 mg/L initial concentration. The adsorption on BPS biochar reached an earlierequilibrium time (90 min) as compared to the BPS biosorbent (110 min). The calculatedmaximum adsorption capacity, q??, using the Langmuir model is 59.52 mg/g and 71.94 mg/gfor BPS biosorbent and BPS biochar, respectively. Isotherm adsorption data for both adsor-bents were better fitted to the Freundlich model. Therefore, the prepared BPS biochar hasgreat potential as a promising adsorbent for removing CV dye from an aqueous solution. |
