Biosorption of acid brown 14 dye to mandarin-CO-TETA derived from mandarin peels

Abstract Several agronomic waste-materials are presently being widely used as bio-adsorbents for the treatment of toxic wastes such dyes and heavy metals from industrial activities, which has resulted in critical global environmental issues. Therefore, there is a need to continue searching more effective means mitigating these effluents. Synthetic aromatic Acid Brown (AB14) dye one effluent that causing serious issue owing huge amount unsafe effluents released into ecosystem daily contaminants. Consequently, their confiscation environment critical. Hence, this study, Mandarin-CO-TETA (MCT) derived mandarin peels was utilized removal AB14 dyes. The synthesized biosorbent subsequently characterized employing FTIR, TGA, BET, SEM coupled with an EDX. biosorption observed be pH-dependent, optimum noticed at pH 1.5 ascribed electrostatic interaction between positively charged sites on anionic dye. process ideally described by pseudo-second-order (PSO) Langmuir (LNR) models. ideal capacity calculated 416.67 mg/g indicative monolayer sorption MCT biosorbent. Thus, studied can employed low-cost activated biomass-based activities before they further environment, thus contamination.
