PET, one of the most commonly used plastics, presents significant environmental challenges due to its non-biodegradable nature. To address this, we developed a sustainable method convert PET waste into high-performance activated carbon via chemical activation with phosphoric acid (H3PO4). The produced was analyzed utilizing X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), nitrogen adsorption/desorption (BET), energy-dispersive (EDX), and Raman spectroscopy. had macroporous architecture substantial surface area, pore diameter, volume 655.59 m2/g, 3.389 nm, 0.120 cm3/g, respectively. adsorption isotherm for phenol conformed Langmuir model, signifying single-layer maximal capacity 114.94 mg/g, while kinetic adhered second-order model at an optimal pH 7. study highlights benefits mitigating plastic pollution producing cost-effective eco-friendly adsorbent water treatment applications. This research underscores potential recycling valuable materials remediation.

Abstract The persistence of tetracycline (TC) in water poses environmental risks, including antibiotic resistance, necessitating effective removal. This study explores the synthesis and application activated carbon from copper pod tree leaves for TC adsorption. adsorbent was produced through orthophosphoric acid activation at low temperature characterized using multiple techniques. FESEM revealed a porous structure favorable adsorption, while EDS confirmed presence carbon, oxygen, phosphorus. FTIR identified hydroxyl carbonyl groups facilitating hydrogen bonding with TC, enhancing XRD adsorbent’s amorphous nature, BET high surface area (865.06 m²/g). XPS further C–O C = O bonds, supporting Kinetic experiments showed that adsorption fitted to pseudo-second-order kinetics (R² 0.9765), indicating chemisorption as dominant mechanism. isotherm modeling results indicated Langmuir model provided an excellent fit experimental data 0.9952), demonstrating monolayer capacity 103.32 mg/g. Thermodynamics spontaneity endothermicity ΔH° 50.75 kJ/mol. prepared effectively removed across natural matrices, retaining performance after five regeneration cycles.
