A research group from the Department of Applied Chemistry and Chemical Engineering studied Ophiorrhiza mungos mediated AgNPs (Om-AgNPs) have been shown to be an effective bio-adsorbent for methylene blue dye removal (88.1±1.74%) after 1h at room temperature in the dark from an aqueous medium for the first time. The biosynthesized adsorbent was successfully reused up to the fifth cycle. A proposed reaction mechanism for the adsorption process of MB dye onto Om-AgNPs is suggested. The present study may offer an effective and sustainable approach for the removal of methylene blue dye from water using bio-synthesized Om-AgNPs as reusable adsorbent at a comparatively faster rate at a low dose for industrial applications.
