The flame atomic absorption spectrometry was used for quantitative determination and study of the ions Pb(II) and Cd(II) adsorption on the solid phase. The Fourier transform infrared spectroscopy (FT IR) was used to investigate the sisal structure and the specific BET surface area was analyzed. The biosorption potential of sisal as biosorbent for the removal of the ions Pb(II) and Cd(II) from aqueous solution was investigate considering the followings parameters: pH, biomass amount and contact time. Langmuir and Freundlich isotherms were used to evaluate adsorption behavior of the ions on this solid phase. The results showed that sisal has a surface area to adsorption of 0.0233 m2g−1, and the OH and CO functional groups are the main involved in the biosorption. The best interpretation for the experimental data was given by Freundlich isotherm that proposes a monolayer sorption with a heterogeneous energetic distribution of active sites, accompanied by interactions between sorbed molecules. The maximum monolayer biosorption capacity was found to be 1.85 mg g−1 for Cd (II) and 1.34 mg g−1 for Pb (II) at pH 7 and 296 K. This phase solid can be used for biosorption of cadmium and lead in polluted natural waters.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-02-29T18:20:43Z No. of bitstreams: 1 Biosorption of Pb(II) and Cd(II) ions by Agave sisalana (sisal fiber).pdf: 270083 bytes, checksum: 29dea35cd007790c0576c3d8235d8c7d (MD5)Made available in DSpace on 2012-02-29T18:20:43Z (GMT).
