"Lead removal from synthetic wastewater by biosorbents prepared from seeds of Artocarpus Heterophyllus and Syzygium Cumini". Chemosphere, 287.0045-65351879-1298https://doi.org/10.1016/j.chemosphere.2021.132016https://www.sciencedirect.com/science/article/pii/S0045653521024887https://hdl.handle.net/11452/39087The present investigation deals with removal of lead (Pb+2) ions from waste water using biosorbent prepared from seeds of Artocarpus heterophyllus (SBAh) and Syzygium cumini (SBSc). Biosorbents surface has been characterized through FT-IR spectroscopy to probe the presence of functional groups. Response surface methodology enabled optimized conditions (Pb+2 concentration 2 mu g/mL, pH 5.8 and bioadsorbent dose 60 mg) resulted in Pb+2 removal similar to 96% for SBAh and similar to 93% for SBSc at agitation speed 300 rpm. The adsorption capacity has been found to be 4.93 mg/g for SBAh and 3.95 mg/g for SBSc after 70 min. At optimal experimental conditions, kinetics of biosorption was explained well by inter-particle diffusion model for SBAh (R-2 = 0.99) whereas Elovich model best fitted for SBSc (R-2 = 0.98). Further, both the biosorbents followed Temkin adsorption isotherm model.eninfo:eu-repo/semantics/closedAccessBiocharBio-sorbentLead removalSeedsAqueous-solutionHeavy-metalsAdsorptionPB(II)IonsBiosorptionEfficientBiosorbentsKineticsSorptionArtocarpus heterophyllus (SBAh)Syzygium cumini (SBSc)Artocarpus heterophyllusSyzygium cuminiLead compoundsArtocarpu heterophylli (SBAh)Optimized conditionsResponse-surface methodologySynthetic wastewaterSyzygium cumini ((SBAh) and syzygium cumini)DiffusionFTIR spectroscopyFunctional groupPlantWastewaterWastewater treatmentChemicals removal (water treatment)AdsorptionArtocarpusHydrogen-ion concentrationKineticsLeadSeedsSpectroscopy, fourier transform infraredSyzygiumWaste waterWater pollutants, chemicalArticle0007047950000082-s2.0-8511429468528734523437Environmental SciencesBiosorption; Isotherms; Aqueous SolutionLeadAdsorption kineticsArticleArtocarpus heterophyllusBiosorptionConcentration (parameter)Controlled studyDiffusionFourier transform infrared spectroscopyIsothermpHPlant seedResponse surface methodSyzygium cuminiVelocityWaste component removalWaste water managementAdsorptionArtocarpusChemistryInfrared spectroscopyKineticsSyzygiumWastewaterWater pollutant
