Abstract The removal of congo-red dye from waste water is crucial due to its toxicity and environmental impact. Adsorption of commercial alumina using Congo red dye was studied at various concentrations and pH. This study investigates the use of aluminum beads as a low-cost and eco-friendly adsorbent for Congo red adsorption. The result of the study shows that aluminum beads exhibit high adsorption capacity at 2.51 mg/g at 6.5 pH with 94% removal. The study revealed that the adsorbed dye was effectively removed using aluminum beads; therefore, this research demonstrates the potentiality of aluminum beads as a sustainable adsorbent for the removal of congo-red in waste water, as alumina gets protonated from acidic solutions, inhibiting the process. Adsorption decreased with increasing initial dye concentrations. Adsorbent dosage also affected adsorption, with increased dosage of aluminum beats which inhibited active sites and decreasing total adsorption due to the decreased surface area available for Congo red dye.Keywords: Congo-red dye, aluminum beads, waste water, adsorption capacity.
