Microwave adsorption of lead from water using lanthanum iron sulfide nanocomposite

Abstract

A novel, quick approach to the synthesis of the monoclinic lanthanum iron sulfide La32.66 Fe11S60 nanocomposite was employed for water contamination remediation for the first time. One of the most harmful contaminants in the water is lead. La32.66 Fe11S60 nanocomposite is utilized to remove lead from water by adsorption under the pH, contact time, sorbent quantity, ion concentration of metal, and ion interference. The produced nanocomposite La32.66 Fe11S60 has been identified using scanning electron microscopic (SEM) and X-ray diffraction (XRD). The highest metal capacity was achieved at pH 5 and 20 s for the lead with 2450 μmol g−1. Kinetic analysis and adsorption isotherm analysis shows were studied in this work.
