Abstract—The adsorptive removal of Malachite Green (MG) using Bamboo-derived Activated Carbon (BAC) was investigated. Bamboo biochar was chemically activated with KOH and carbonized at 700 °C for 3 h to produce BAC. The prepared material was characterized using Scanning Electron Microscope (SEM), Carbon, Hydrogen, Nitrogen, Sulfur (CHNS), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), and Brunauer Emmett Teller (BET) analyses. Batch adsorption experiments were conducted using an adsorbent dosage of 0.25 g in 50 mL of MG solution to evaluate the effects of initial dye concentration and contact time on adsorption performance. The characterization results confirmed that BAC possesses favorable surface and textural properties for MG adsorption. Adsorption equilibrium was achieved within 60 min, and the equilibrium data were better described by the Langmuir isotherm model than by the Freundlich model, indicating that MG adsorption occurs predominantly via a favorable monolayer physisorption mechanism.
