Due to the intense industrialization of the modern society, severe contamination of water by dangerous metal ions has become a major problem. The use of plant-derived biosorbents has been proposed in different studies in reason of their good performance and marginal cost. The proposal of this study was to evaluate the use of spent coffee ground (SCG) for the removal of metal ions from aqueous effluents. The batch process showed removal efficiencies equal to 92.4% for Al3+ and 85.9% for Fe2+,doi:10.46814/lajdv4n3-039 fatcat:mnzrtc5lubcbhl4b2nhgqfdwr4
