A carbon-based material was synthesized using potato peels (BPP) and banana pseudo-stems (BPS), both of which were modified with manganese to produce BPP-Mn BPS-Mn, respectively. These materials assessed for their ability activate peroxymonosulfate (PMS) in the presence MnCO3 degrade acetaminophen (ACE), an emerging water contaminant. The underwent characterization spectroscopic, textural, electrochemical techniques. Manganese served a dual function: enhancing adsorption properties facilitating breaking peroxide bonds. Additionally, carbonate ions played structural role materials, transforming into CO2 at high temperatures thereby increasing porosity, improved capabilities. This presents notable advantage that have not undergone de-lignification. Among tested, BPS exhibited highest efficiency carbocatalytic degradation ACE, achieving synergy index 1.31 within just 5 min, 42% ACE compared achieved 100% removal through adsorption. Reactive oxygen species such as sulfate, hydroxyl, superoxide anion radicals identified primary contributors pollutant degradation. In contrast, no observed BPP BPP-Mn, is likely linked lower lignin content precursor material. work addressed challenge revalorizing lignocellulosic waste by highlighting its potential oxidant pollutants. Furthermore, study demonstrated coexistence various reactive species, confirming capacity matrices PMS.
