Dr. Gunjan Bisht Thapa, Assistant Professor of Department of Chemical Science and Engineering with her student Ms. Sanjila Neupane of Department of Environment Science and Engineering, published a research article entitled “Arsenic removal through supercritical carbon dioxide-assisted modified magnetic starch (starch–Fe3O4) nanoparticles” in  a peer reviewed journal Nanotechnology for Environmental Engineering (Springer).

This study employs starch as biopolymer for coating onto MNPs (Fe3O4) surface and reports a noble method for preparation of starch-modified magnetic nanoparticles (starch-MNPs) in supercritical carbon dioxide reactor. The adsorption capacity of synthesized NPs for arsenite    [As (III)] was investigated by varying pH, temperature, adsorbent dose and analyte concentration as a function of contact time. Besides, reusability study of synthesized NPs was estimated and was utilized in field samples to compare their efficacy in total arsenic removal.
