Abstract

Alginate blended with cellulose nanocrystals (CNC), cellulose nanofibers (CNF), and tri-carboxylate cellulose nanofibers (TPC-CNF) prepared and encapsulated in the form of microcapsules (bio-polymeric beads). The cellulosic nanomaterials that used in this study were investigated as nanomaterials for wastewater treatment applications. Batch experiments were performed to study the removal of copper, lead, magnesium, and iron from aqueous solutions by the prepared beads. The effects of the sorbent dosage and the modified polymers on the removing efficiency of the metal cations were examined. Atomic absorption was used to measure the metal ions concentrations. The modified bio-polymeric beads (Alg-CNF, Alg-CNC, and Alg-TPC-CNF) exhibited high-efficiency towards removing of the metal cations; Cu2+, Pb2+, Mg2+, and Fe2+. The Alg-TPC-CNF composite was exhibited excellent removing efficiency which around 95% for Pb, 92% for Cu, 43% for Fe and 54% for Mg. These outcomes affirm that the utilization of nanomaterials giving higher adsorption capacities contrasted with similar material in its micro or macrostructure form.
