Description
Summary:Due to increasing contamination of water and soils by industrial production, there is a crucial need for new natural sorbents that are cost-effective, environmental friendly for pollutant removal. In this context, Moroccan oil shale from Tangier Region (OST) was characterized and evaluated for methylene blue (MB) remediation as model for cationic dye. The maximal sorption capacity of the dried OST100 (>100 mg g–1) is higher than that of calcined OST550 (80 mg g–1) and OST950 (60 mg g–1) samples. The pseudo-second-order kinetic model and Freundlich equation were found the most adequate to reproduce the experimental data. The effect of the thermal treatment of this oil shale on its sorption capacity was investigated, demonstrating that the active sites from shale play an important role for MB removal. As a result, this natural, widely available and low-cost resource can be a good adsorbent used for many removal applications of specific pollutants.
