leaves (MOL) for the removal of Pb (II) from aqueous solutions. The MOL biomass was
characterized by FTIR, SEM, EDX, and BET. The impact of initial concentrations of Pb (II),
adsorbent dosage, pH, contact time, coexisting inorganic ions (Ca2+, Na+, K+, Mg2+,
CO32−, HCO3−, Cl−), electrical conductivity (EC) and total dissolved salts (TDS) in water
was investigated. The results revealed that maximum biosorption (45.83 mg/g) was …
