Development of a novel in-situ aluminum/carbon composite from olive mill wastewater for the selective adsorption and separation of malachite green and acid yellow 61.

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.
