In this study, an aluminum/carbon composite was developed from olive mill wastewater (OMWW) and successfully applied in the removal/separation of malachite green (MG) and acid yellow 61 (AY61) and in the treatment of a real discharge from a denim dye bath. The optimized composite (0.5% Al) is microporous, has a specific surface area of 1269 m.g, rich in anionic sites, has an adsorption capacity of 1063 mg.g and exhibited efficient separation of AY61/MG. Thermodynamic results showed physical, endothermic and disordered adsorption. The substrates were attached to the surface by electrostatic, hydrogen and π- π interactions through the contribution of multiple sites in parallel and non-parallel orientations. The composite can be used repeatedly without significantly losing its performance. This study, presents an exploitation of agricultural liquid waste to develop carbon composites for industrial dye removal and separation, creating new economic opportunities for farmers and rural communities.
在这项研究中，从橄榄石磨废水（OMWW）开发出一种铝/碳复合材料，并成功应用于去除/分离孔雀石绿（MG）和酸性黄 61（AY61）以及处理牛仔布染色浴的实际排放物。优化的复合材料（0.5%Al）是微孔的，比表面积为 1269 m.g，富含阴离子位，吸附容量为 1063 mg.g，并表现出对 AY61/MG 的有效分离。热力学结果表明，吸附是物理的、吸热的和无序的。底物通过静电、氢键和π-π相互作用附着在表面上，这是通过多个平行和非平行取向的位点的共同作用实现的。该复合材料可以重复使用而不会显著降低其性能。本研究利用农业废液开发用于工业染料去除和分离的碳复合材料，为农民和农村社区创造新的经济机会。
