| description | Chromium (Cr) is a toxic heavy metal present in industrial effluent which could cause degenerative diseases on ingestion.
Therefore, elimination of Cr from contaminated water becomes essential to preserve and sustain the quality of life. In this
study, superparamagnetic iron oxide nanoparticles (SPIONs) were impregnated on activated carbon and checked for enhanced
removal of Cr(VI). Thus, granular activated carbon (N-GAC) of mesh size 8 ∗ 20 was impregnated with SPIONs to produce
SPIONs impregnated activated carbon (Sp-GAC) and characterized using UV-VIS spectrophotometer, FT-IR, SEM-EDX, XRD,
and VSM. Sp-GAC was found to be possessing superparamagnetic behavior, and it was used in batch adsorption study where
the adsorption parameters like pH, concentration of adsorbent, and adsorbent-adsorbate were optimized. It was found that
Cr(VI) adsorption was predominant at acidic pH (pH 3) for both cases; moreover, N-GAC showed better adsorption
comparatively. Both the N-GAC and Sp-GAC adsorption were found to be obeying to Langmuir. |
