Biological materials play a significant role in the treatment of heavy metal-contaminated soil and wastewater. In this study, the Pb biosorption potential of lichen Evernia prunastri, extensively available at a forest in Bilecik-Turkey, was investigated at batch-scale level. The optimal conditions were determined and the adsorption isotherms, kinetics, and thermodynamic calculations were also done. In order to have detailed knowledge about metal biosorption, SEM, FTIR, and BET analyses were carried out before and after the biosorption process. The optimal pH was found pH 4 and the maximum metal uptake capacity was found as 0.067 mol kg. The results of this study indicate that the lichen was effectively applied to the removal of Pb process as an inexpensive biosorbent from industrial wastewater.
生物材料在处理重金属污染土壤和废水方面发挥着重要作用。本研究在批量水平上，调查了广泛存在于土耳其比莱吉克森林中的地衣短梗霉对 Pb 的生物吸附潜力。确定了最佳条件，并进行了吸附等温线、动力学和热力学计算。为了详细了解金属的生物吸附，在生物吸附前后进行了 SEM、FTIR 和 BET 分析。发现最佳 pH 值为 pH 4，最大金属吸附容量为 0.067 mol kg。本研究结果表明，地衣作为一种从工业废水中去除 Pb 的廉价生物吸附剂，可有效地应用于去除 Pb 过程。
