Structural, thermodynamics, and mechanistic insights into a tobacco-waste derived activated carbon/polysaccharide composite sponge for efficient Cr(vi) adsorption and reusability.

ABSTRACT: This study presents the creation of an innovative bioadsorbent a porous carbon-polymer composite, referred to as TACGC, was synthesized utilizing residues from tobacco processing and subsequently assessed for its efficacy as an adsorbent of hexavalent chromium (Cr(vi)) from aqueous solutions. The composite was fabricated by integrating tobacco-derived activated carbon into a matrix composed of guar gum and carboxymethyl cellulose, which was chemically cross-linked with itaconic acid, resulting in a stable and functional sponge-like structure. The structural and surface characteristics were investigated through various analytical techniques, including XRD, FT-IR, XPS, SEM-EDX, and BET analysis. These analyses collectively confirmed the development of a mesoporous network characterized by an
