Özet
In recent years, the removal of heavy metals from water by using low-cost agricultural waste activities were accelerated. In the present study, pistachio shell (PSS) was used to remove Pb(II) from aqueous solution using batch experiments. Some parameters such as dose of the adsorbent and pH of solution were investigated in order to know the room temperature, 100 mg/L initial Pb(II) concentration and, particle size of between 0.5 and 2.0 mm and adsorption ability of the adsorbents. The removal efficiency of Pb(II) ions was found to 9.71 mg/g of PSS. The results of isotherm and kinetic studies show that the Langmuir isotherm and pseudo-second-order kinetic showed better correlations with the experimental data. The SEM images of adsorbent (PSS) before and after Pb(II) adsorption were analysed to understand the adsorption process of Pb(II) onto PSS. These results suggest the PSS turned out to be effective natural low-cost adsorbent for capturing of Pb(II) ions from aqueous environment.
