| Abstract | The adsorption of malachite green (MG) from synthetic wastewater on banana peel adsorbent was studied in batch experiments. Two species of banana peel adsorbents (Musa x paradisiaca, ABB and Musa acuminate, AAA) with two maturation stages (2 and 6) were studied. The best efficiency of MG removal (97.64%) was obtained using the powder of ripe ABB banana peel (stage 6) as the adsorbent under the optimal conditions of pH 5, 12 h equilibrium time, initial dye concentration of 25 mg/L, adsorbent particle size of 0.150-0.212 mm at the dose of 1 g/L, 30 ?C, and shaken at the speed of 150 rpm. The experimental results were best described by the Freundlich isotherm model and the pseudo-second-order kinetic model. Thermodynamic results of the adsorption revealed that it was a random, endothermic, and spontaneous process under the investigated temperature range. |
