Publisher: | PCSIR-Scientific Information Centre | Abstract: | An indigenous biosorbent originated from orange peel was scrutinized the remediation of hexavalent chromium (Cr+6) from industrial effluents. The analytical influences of different biosorption parameters such as biosorbent dosage, contact time, Cr+6 concentration, pH and temperature were also studied. The physical modeling study revealed that the biosorption of Cr+6 on orange peel biosorbent (OPB) followed the rate of kinetic pseudo second order with a multilayer biosorption. Meanwhile, the estimated mean sorption energy (E) indicated the chemisorption surface mechanism for the biosorption of Cr+6 on the surface of OPB. The thermodynamic changes of Gibbs free energy, enthalpy and entropy showed a spontaneous and exothermic biosorption of Cr+6 onto the OPB. The studied material of OPB showed an efficient removal of Cr+6 from collected industrial effluents with % biosorption Cr+6 up to 94%. The experimental adsorption capacity of Cr+6 on OPB is 0.222 mmol/g with negligible interference. The proposed OPB is found to be an economical biosorbent for the efficient removal of Cr+6 ions and successfully applied on different industrial effluents with biosorption > 94%. © 2022 PCSIR-Scientific Information Centre.
