Antibiotics (ANTs) deep purification using pyrolytic carbons (PyCs) has been demonstrated as a promising strategy. Since PyCs structural modification is the key to enhancing their capacity, underlying mechanisms need be further clarified. Here, three nitrogen-doped porous with solid-sphere, hollow-sphere, and bowl-shape were prepared soft-template-KHCO3 copyrolysis method. The bowl-shaped bNPyC, BET/micropore surface area of 2072.79/1415.9 cm2/g, showed highest adsorption capacity for sulfamethoxazole (SMZ, Qfitted, max = 5.44) ciprofloxacin (CIP, 3.23 mmol/g) rapid equilibrium. Despite slight N doping (0.69%), SMZ/CIP on bNPyC improved significantly 48.6%/64.2%. Additionally, outperformed other reported in Q/N exposure value. exhibited excellent performance ANTs across wide pH range 2–10, particularly CIP. interactions semiquantitatively identified by probe competition experiments confirmed spectra characterizations density functional theory calculations. Mechanism analysis revealed that facilitates not only π–π EDA but also charge-assisted H-bond between ANTs. anti-interference properties, recyclability, universality removal demonstrated. These findings may guide design deepen our understanding structure–property mechanism ANT PyCs.

With the growth of global population and acceleration industrialization, problem water pollution has become increasingly serious, posing a major threat to ecosystem human health. Traditional treatment technologies make it difficult cope with complex pollution, so scientific community is actively exploring new efficient methods. Biochar (BC), as low-cost, green carbon-based material, exhibits good adsorption catalytic properties in due its porous structure abundant active functional groups. However, BC's pure or capacity limited, researchers have dramatically enhanced performance through modification means, such loading metals heteroatoms. In this paper, we systematically review recent applications BC modified materials for adsorption, Fenton-like, electrocatalytic, photocatalytic, sonocatalytic systems, discuss their adsorption/catalytic mechanisms. most research field at laboratory simulation stage still needs much improvement before can be applied large-scale wastewater treatment. This improves understanding pollutant mechanisms BC-based materials, analyzes limitations current studies, investigates future directions.

Olive mill waste (olive pomace, OP, and olive stone, OS) was used in this work to produce adsorbents for the removal of five phenolic acids typically found wastewater. OP OS were subjected different treatments (combined or not) that chemically modified (NaOH) physically by two methods, incipient wetness impregnation (IWI) hydrothermal deposition (HD), even biochar production obtaining a total 16 materials. The materials characterized analytical techniques such as N2 absorption, scanning electron microscopy, infrared spectroscopy, pH zero-potential charge. mixture evaluate batch conditions adsorption capacity prepared with IWI (OSM-IWI) HD (BOS-HD) presented better at 157.1 163.6 mg/g acids, respectively, from 200 mg/g. For some materials, surface area cannot be correlated capacity, unlike pHzpc, where high values fit rates. spectroscopy profile indicates presence O-H N-H functional groups and, last one, red-shifted preparation compared one. In addition this, material can suitably compounds.
