چکیده مقاله :
Interaction of Pb(II) ion with modified banana shell (MBS) and banana shell (BS) during adsorption fromaqueous solution were investigated. Batch experiments were carried out to investigate the effect of contact time,pH, and IDMID ion concentration on adsorption efficiency. The favorable pll for maxim= Pb(II) adsorptionwas at 5.0. For the investigated IMOI) concentrations (10-80 mph), maximum adsorption vacs were achievedalmost in the 100 min of contact. Lanpnuir, Freundlich, and Redlich-Peterson were fitted to equilibrium datamodels. According to values of error functions and correlation coefficient, the Langmuir and Redlich-Petersonmodels were mon: appropriate to describe the adsorption of Pb(II) ions on MRS and BS. The monolayermaximum adsorption capacity of Pb(II) ions was determined as 104.2 and 453 mgig for MRS and BS.respectively. Results indicated that theSc adsorbents had a great potential for removing of Pb(11) ions as an ecofriendlyprocess
