摘要

Discharging phenolic wastewater into water bodies induces severe environmental impacts alongside with high hazardous health threats. In order to achieve sustainability, several agrowastes including mango biochar (MBC), lemon biochar (LBC), banana biochar (BBC) and their corresponding magnetic counterparts, coded -in the same sequence- as (mMBC), (mLBC) and (mBBC) were applied for the removal of phenol from simulated solution under different variables. All the adsorbents were extensively characterized using different analytical tools in order to investigate their structure-performance relationship. In addition, the reusability of the adsorbents was investigated for five successive cycles. The removal process was verified via different kinetic models and isotherms to underscore the nature of adsorption course. The data reveals that the maximum removal of phenol was attained at the following optimum conditions: pH6 for (MBC, mMBC) and (BBC, mBBC) and at pH4 for (LBC, mLBC), contact time 180 minutes for (MBC, mMBC), 120 minutes for (LBC, mLBC) and 90 minutes for (BBC, mBBC) while the adsorbent dose was constant (0.2g) for all investigated materials. In addition, it was found that the adsorption process fitted the pseudo 2nd order model suggesting chemisorption process. The experimental findings proved very acceptable removal performance in comparison to other agrowastes and that the maximum removal capacities ranging from 23.06 to 46.63 mg.g. Furthermore, the investigated sorbents were applied for treatment of a real petroleum wastewater sample. The data proved their potential in enhancing the physicochemical properties of the polluted sample and the maximum phenol removal was 94.8%.
