In the last decade, the expansion of industrial and agricultural activities has led to the significant rise of organic pollutants, contributing to serious environmental contamination. Biochar has received considerable attention as a low-cost and environmentally friendly adsorbent for a wide range of pollutants. In this...
Driven by the need to develop innovative solutions for wastewater treatment and to reduce waste generation, this study proposes the valorization of agricultural residues, specifically peanut shells, as a precursor for the synthesis of surface-area activated carbon (AC) through chemical activation with KOH (ratio 1:3)....
Increasing concerns about water pollution have highlighted the importance of developing new methods for wastewater treatment. From a green and sustainable point of view, biochar is classified as one of the most important candidates for wastewater treatment. This study used Harmal as a waste feedstock to prepare bio...
Industrial development has contributed to heavy metals, a main environmental pollutant, being present in most effluents. These elements are extremely toxic and persistent, representing a serious threat to human health if left untreated. An effective alternative for the removal of metals from water is the adsorption tec...
This work investigates a circular economy strategy by converting sewage sludge into efficient adsorbents for malachite green (MG) removal. The adsorption performance of raw sludge (RS) was compared with NaOH‐activated biochar (NAB) prepared by pyrolysis and chemical activation. Physicochemical characterization (XRF...
