What is Treatment of heavy metal ions-polluted water into drinkable water: Capture and recovery of Pb2+ by cellulose@CaCO3 bio-composite filter via spatial confinement effect about?
A bio-composite of cellulose@CaCO3 (Cel@CaCO3) has been prepared via a facile precipitation reaction route, in anticipation of solving the toxic lead ion pollution problem and satisfying the sustainable development. The microstructures along with the morphology were characterized by XRD, FT-IR, SEM and TEM. It is found that CaCO3 forms the hydrogen bonding with cellulose in the composite, which makes it cover on the cellulose fibers. This would construct a suitable micro-environment for the Pb2+ capture and removal due to the spatial confinement effect. The high performance has been achieved with the up-taken capacity of 602.3 mg·g−1. When treating the wastewater with the Pb2+ concentration less than 50 mg·g−1, almost 100 % removal rate was obtained only within 10 min. The Pb2+ ions were trapped on the surface of cellulose and appeared as the form of PbCO3. Consequently, the complete separation and recovery would be accomplishable without the secondary pollution, for the spent bio-composite filter was removed easily and conveniently. Notably, the treated water met the drinkable criterion. The roles of cellulose and removal mechanism have also been explained in details.
