Synthesis of magnetite from raw mill scale and its application for arsenate adsorption from contaminated water

The magnetite particles were chemically synthesized from the waste of hot rolling steel industry. The characterization of the synthesized magnetite was done by using Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Energy Dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). The synthesized magnetite particles were used for the adsorptive removal of arsenate from…

Evaluation of arsenate adsorption efficiency of mill-scale derived magnetite particles with column and plug flow reactors

Magnetite particles were synthesized by co-precipitation method from the mill-scale and characterized with FTIR, SEM, EDS and XRD. The proficiency of magnetite particles for arsenate removal is determined with batch adsorption experiments and various types of continuous reactors including column reactor fed from bottom to top, column reactor fed from top to bottom and plug…

Packed Bed Column for Adsorption of Arsenic on Mixed-Valent Iron [Fe(II)-Fe(III)] Oxide Synthesized from Industrial Waste

Hundreds of millions of people in the world regularly intake groundwater that has a high-risk arsenic level. In several parts of Asia, the arsenic concentration reaches up to μ, which is above the drinking water standards of the World Health Organization (μ). The present study discusses the arsenic removal from groundwater using a mixed-valent iron…
