Article Synopsis
- Almond shell-based biocarbon is an effective and inexpensive adsorbent for removing malachite green dye, characterized using FT-IR, DRX, and BET techniques, revealing a surface area of 120.21 m²/g.
- The adsorption studies indicate that the process fits the Langmuir isotherm and pseudo-second-order kinetic model, achieving a maximum capacity of 166.66 mg/g at specific conditions (adsorbent mass of 0.1 g, dye concentration of 600 mg/L, and temperature of 25 °C).
- The positive ∆H value (12.19 J/mol) indicates that the adsorption process is endothermic, and the D-opt
