Discharge of dye-containing wastewater from various industries like textile, leather, paint, cosmetics etc. industries contributes to large amounts of pollution, leading to serious environmental problems such as quality deterioration of fresh water and endangering ecosystems' health. One of the conventional anti-fungal agent in aquaculture which should be eliminated from wastewaters prior to releasing it into natural water resources. Tremendous volumes of colored wastewater are generated in textile, leather, paint, cosmetics etc. industries, causing eternal damage to the water resources. Wastewaters released from dye production and application industries are responsible for water pollution. Untreated disposal of the colored water into receiving water body causes damage to aquatic life and human bodies. Due to the high toxicity of dyes at low concentrations, they must be treated before being discharged into the receiving body of water. Therefore, environmental legislation has imposed severe limits on the discharged effluents' concentrations from dyestuff manufacturing and textile industries. تفاصيل المقالة

This research addressed the elimination of the dye Congo red (CR) from an aqueous solution utilizing dried palm leaf activated carbon (PLAC). Therefore, we performed batch experiments for isotherms and sorption kinetics. According to the experimental data, the adsorption method largely depends on the equilibrium time, initial concentration of dye, pH solution, and adsorbent amount. We observed sorption equilibrium for the dye Congo red via PLAC in 60 min and an adsorption capacity of 52.1 mg g-1. A pseudo-first-order kinetic model was followed by sorption kinetics, whereas the Langmuir isotherm has been proposed to be help reache the equilibrium factor. The above data demonstrated that PLAC is an effective, low-cost, and environmentally friendly biomaterial for removing the dye from the aqueous solution. تفاصيل المقالة
