Use of Alginate-Moringa oleifera Beads on Cu (II) and Cd (II) Adsorption from Aquatic Systems

Abstract—In this paper, we present the results of Cu (II) and Cd (II) removal by alginate immobilized Moringa oleifera beads. The beads were separated in two fractions, dried and soaked ones. Equilibrium and kinetic experiments were conducted to determine maximum adsorption capacity under various experimental conditions. A sorption capacity of 67.0 mg.g-1 was obtained using 10 units of dried beads on 20 mg.L-1 Cu (II) and of 60.0 mg.g-1 was obtained using 15 units of dried beads on 23 mg.L-1 Cd (II). In conclusion, alginated – Moringa oleifera beads show to be an efficient adsorbent on aquatic system, with more than 90% of efficiency of removal. And biosorbent regeneration demonstrated to be efficient and maintained its adsorption capacity for seven cycles.

Index Terms—Adsorption, heavy metals, natural coagulant, Moringa oleifera.
