Water contamination by heavy metals has harmful and hazardous health consequences for humans. The goal of this study is to see how effective Moringa seeds beads (MOSB) mixed with sodium alginate are at adsorbing ions like copper, nickel, manganese, lead and fluoride from polluted water. Different instrumental approaches were used to characterize the adsorbent (FT-IR and SEM).. Batch adsorption studies and the effects of the adsorption parameters were optimized. The results revealed that the removal rate for each element occurred at the optimum dose (5g/l) with removal efficiency (93, 72, 80, 96, and 93 %) and the maximum sorption capacity (Qmax.) of about (12.5, 8, 8.3, 13, and 13 mg/g) for copper, nickel, manganese, lead and fluoride ions, respectively. The pH, coagulant dosage, mixing, concentration, and the initial turbidity of the water all had an impact on the removal of heavy metals and fluoride ions. MOSB can be considered as sustainable alternative material because it is inexpensive, requires no prior treatment, and it is a bio-sorbent for removal of heavy metals and fluoride ions from wastewater.
