Biosorption of heavy metal ions from the aqueous solutions using groundnut shell activated carbon: batch adsorption, kinetic and thermodynamic studies

<p>Batch adsorption studies of heavy metals were carried out using activated charcoal groundnut shell powder as an adsorbent material. The was collected and synthesized by chemical synthesis to convert it into form. prepared adsorbent’s pore size & surface area analyzed BET analysis N2 – desorption process. XRD techniques the crystalline structure adsorbent, functional groups behaviour through FTIR, SEM, EDX analysis. optimum parameters pH, temperature, time contact between adsorbate, dose, metal ion concentrations obtained from batch studies, mass transfer mechanism rate-controlling step identified isotherm kinetic studies. Thermodynamic confirm endothermic nature process spent ions have been recovered concentrated sulfuric acid.</p>
