Sequestration of Cr(VI) onto polyethyleneimine-derivatized cellulose and its effect on the enzymatic degradation and microbiome viability.

The extremely hazardous nature of Cr(VI) necessitates its sequestration in a sustainable and effective manner. Cellulose-derived materials, known for their eco-friendly properties, are widely employed in environmental remediation. To improve its adsorption capabilities for heavy metals, cellulose is often derivatized with moieties like amine, thiol, carboxylic acid, etc.
