Abstract

The ability of sheep wool to remove Pb(II) ions and safranin dye from aqueous solutions through the adsorption process was investigated at room temperature. The metal ions concentration was determined by flame atomic absorption spectrophotometer method. The influence of pH, contact time, amount of adsorbent, temperature and initial metal ions concentration were examined by the batch method. The experimental data were analyzed using the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherm equations. The correlation coefficients were determined by analyzing each isotherm. The results indicate that the experimental data show better correlation with the Freundlich isotherm for Pb(II) ion and Langmuir isotherm for safranin dye than other isotherms. Thermodynamic parameters such as Gibbs free energy enthalpy and entropy have also been evaluated and it has been found that the sorption process was feasible, spontaneous and exothermic. The maximum amounts of Pb(II) and safranin dye adsorbed (qm), that show in order of 12.787 mg/g for Pb(II) and 4.6533 mg/g for safranin of wool sheep. The morphological analysis of the wool sheep was performed by the Scanning Electron Microscopy (SEM).
