A Study on Heavy Metal Ion Adsorption, Antibacterial and Anticancer Activities of Sawdust Chitosan Activated Carbon

Sawdust-Chitosan Composite beads (SDCCB), a low-cost non-conventional surface modified activated carbon, has been used for the efficient removal of Cu(II) ions from aqueous solutions. Surface morphology of the sample has been characterized by XRD, SEM, EDAX and FTIR analyses. Batch experiments have been conducted spectrophotometrically in order to determine the maximum adsorption capacity and influence of physicochemical parameters. The experimental data has been fitted with various isotherm and kinetic models to predict the conditions for maximum adsorption. The activation parameters evaluated for this adsorption process propose the adsorption mechanism as feasible, spontaneous, endothermic and increased randomness. Also, the antimicrobial and anticancer activities of SDCCB have been screened by disk diffusion method and MTT assay, respectively.
