AI Insight
This study demonstrates the effectiveness of activated carbon derived from hazelnut husks, prepared using potassium hydroxide (KOH) activation, for removing regorafenib (an anticancer pharmaceutical) from aqueous solutions. The researchers investigated the adsorption process through kinetic, isotherm, and thermodynamic analyses to understand the removal mechanism. The hazelnut husk-derived activated carbon showed promising adsorption capacity for eliminating this pharmaceutical contaminant from water.
Why it matters
Pharmaceutical contamination in water systems is an emerging environmental concern, and regorafenib residues from medical use can enter wastewater. This research provides a cost-effective, sustainable solution using agricultural waste (hazelnut husks) to create an efficient water treatment material, potentially offering an environmentally friendly approach to removing pharmaceutical pollutants from water sources.
