Özet
Accumulating dyes, drugs, and heavy metals in water creates a lasting environmental problem that affects living
things in different ecosystems. Their removal is imperative for environmental necessity in a habitable world.
Adsorption with carbonaceous materials produced especially for the evaluation of agricultural wastes is a lowcost and effective removal technique. This study is related to the investigation of the adsorbing performance
of a new activated carbon (BAC) synthesized from black cumin (Nigella sativa) processing solid waste (BW) under
optimal conditions determined by single-step carbonization/activation with potassium carbonate to remove
methylene blue, oxytetracycline, and lead (II) in an aqueous medium. Their optimum adsorption conditions were
decided based on the maximum effects of important operational parameters. Experimental kinetic and isotherm
findings for each adsorption system were modeled by evaluating widely used kinetic and isotherm equations. The
maximum adsorption capacity of BAC was determined as 752 mg/g for methylene blue, 911 for oxytetracycline,
and 556 mg/g for lead (II) from the Langmuir isotherm model. The thermodynamic parameters determined
showed that the adsorption processes were self-occurring and also endothermic for methylene blue and
oxytetracycline and exothermic for lead(II). In addition, BAC showed stability and recyclability in adsorptiondesorption cycles for the pollutants studied. These findings suggest that BAC can be used as an ultra-efficient
adsorbent for larger-scale wastewater treatment.
