Removal of lead, cadmium, and copper from water using<i>Moringa oleifera</i>seed biomass

Abstract This study demonstrated that Moringa oleifera seed biomass (MOSB) has the potential to be used as a natural alternative in removal of lead (Pd), cadmium (Cd), and copper (Cu) from water which was justified by level toxicity, environmental unfriendliness, costly nature chemical coagulants presently used. The Fourier Transform Infrared (FTIR) analysis identify MOSB functional groups present adsorption metal ions. maximum at pH 5, room temperature, 0.8 g dosage 90, 81.77, 70% for Pb(II), Cd(II), Cu(II), respectively. order biosorption preference Pb(II)&amp;gt;Cd(II)&amp;gt;Cu(II) single sorption is consistent correlation between physiochemical properties ions selective groups. data fitted better Langmuir than Freundlich models capacities (qm) Cu(II) were 6.19, 5.03, 3.64 mg/g, separation factor (RL) within range 0–1 showed processes favourable M. adsorbent. results an effective adsorbent studied heavy metals contaminated water. In all these water-purifying moringa biomass, no deliberate attempt been made use ternary system very toxic like Pb, Cd, Cu knowing anti-bacterial system. Similarly, reproducibility, low cost, requirement power source make this efficient process obtaining potable even homes rural settings.
