Renowned for its versatility in environmental applications, biochar exhibits substantial potential to enhance anaerobic digestion, facilitate carbon sequestration, and improve water treatment through highly efficient adsorption mechanisms. This study focuses on derived from pineapple crown biomass, produced slow pyrolysis, efficiency removing organic dyes contaminated water. The structural, morphological, surface properties of both chemically activated samples were comprehensively characterized using a range techniques, including XRD, FTIR, XPS, BET area analysis, SEM microscopy. performance was evaluated methylene blue (MB), rhodamine B (RhB), malachite green (MG) as model contaminants, with particular emphasis the contact time dye removal efficiency. Initial results showed rates 10.8%, 37.5%, 88.4% RhB, MB, MG, respectively. Notably, chemical activation significantly enhanced efficiency, achieving complete (100%) all tested dyes. Complete MB MG occurred within 9 min, indicating rapid kinetics. Adsorption data fit well pseudo-second-order kinetics (R2 = 0.9748–0.9999), Langmuir isotherm 0.9770–0.9998) suggested monolayer interactions between biochar. intraparticle diffusion further clarified These findings demonstrate efficacy highlight biomass remediation.
