Ziziphus Jujube Seeds derived Biomass as Cost-Effective Biosorbent for the removal of Cr6+ from Aqueous solutions: Isotherm and Kinetic Studies

<p>Biosorption of hexavalent chromium ions from the synthetic solution was performed using activated Ziziphus jujube seeds powder as an adsorbent material. A chemical synthesis process prepared adsorbent, and various methods have evaluated its characteristics. FTIR, SEM EDX analysis conducted to check ability uptake solutions. Batch mode adsorption parameters pH, concentration, dose, contact time temperature were found in operating conditions. The entire by isotherm kinetic models nature reactions. Thermodynamic studies conducted, desorption used recover spent concentrated hydrochloric acid.</p>
