Abstract

Studies on resource assessment of raw materials shows that many agricultural waste raw materials are available to be used as adsorbent material. we were investigated the adsorption factors such as initial concentration (25 to 125 mg/l), pH (2 to 12), temperature (30 to 60°C) adsorbent dose (0.50 to 1.50 gm/l) and particle size (0.05 to 0.5 mm), by using a batch adsorption technique to obtain information on treating effluents from the dye industry. The results showed that Peel Peanuts Activated Carbon (PPAC) was effective, for which the removal reached 99% methylene blue at 30°C. Adsorption of methylene blue was highly pH-dependent (6-8) and adsorption increases with initial MB concentration. Also temperature and smaller adsorbate particle were found to increase the percentage removal of MB, for which the removal reached 99.9% methylene Blue at 60°C. Adsorption of MB on PPAC will fit the Langmuir model, corroborating the assumption of that the adsorbate molecules could be adsorbed in one layer thick on the surface of the adsorbent material. A comparison of kinetic models at different conditions showed that the pseudo second-order kinetic model correlate the experimental data well. The thermodynamic parameter shows that the adsorption process is endothermic. This is in accordance with increasing adsorption rate with increasing temperature.
