A wide range of EOPs are now being detected in surface water and groundwater resources due to recent historical anthropogenic activities (Vashistha, 2022). These pollutants enter the environment through several pathways such as industrial effluent discharge, agricultural runoff, wastewater treatment plants (WWTPs) discharge improper waste disposal (Kuchangi et al., 2023;Shah, 2021). Due their into environment, can harm wildlife, ecosystems, possibly humans (Zhou 2024). Thus, a variety methods have been reported for removal EOPs, particularly using adsorptive photocatalytic degradation utilizing nanomaterials (Mashile 2023;Paumo This Frontiers Chemical Engineering article collection aimed highlight development effective or technologies well application bio-based sorbents monitoring occurrence systems. total four papers contained herewith including two comprehensive reviews research articles related adsorbents photosensitizers water.The collected work represented contributions from leading groups worldwide offering insights direction various photocatalysts.

In this study, manganese–nitrogen sites were incorporated into biochar (BC) to activate peroxymonosulfate (PMS) for the degradation of sulfamethoxazole (SMX). Characterization techniques, including scanning electron microscopy and others, confirmed successful doping Manganese–Nitrogen (Mn–N) BC (referred as MnN@BC). The study revealed that integration Mn–N active in modified electronic polarization facilitated transfer. It is worth noting a remarkable synergistic effect (SI = 6.92) was witnessed MnN@BC/PMS system. Under optimal conditions, SMX nearly completely eliminated within 40 minutes. Radical scavenging experiments indicated Hydroxyl (•OH), Sulfate Radicals (SO4•−), superoxide radicals (O2•−), singlet oxygen (1O2) all played significant roles SMX. Density functional theory calculations employed further investigate mechanism enhanced transfer PMS by loading on site. Cyclic characterizations conducted before after recycling demonstrated MnN@BC exhibited stability reusability. This probed activation transition metal non-metal dual offered strategies more effective sustainable pollutants.

In this work, a novel molecularly imprinted electrochemical sensor was proposed based on molecular imprinting technology for the detection of sulfamethazine. A glassy carbon electrode modified with composite material nanotubes and graphene quantum dots to effectively improve sensitivity. The then prepared by electropolymerization using sulfamethazine as template o-phenylenediamine functional monomer electrode. Under optimal measurement conditions, tests different concentrations (0.5 μM–200 μM) showed excellent linearity limit 0.068 μM. addition, demonstrated satisfactory selectivity, stability, reusability. Furthermore, applied spiked analysis in grouper aquaculture water, achieving recovery rates between 95.4% 104.8%, relative standard deviation (RSD) less than 4.14%. These results indicated that developed method effective seawater, providing new approach antibiotic residues seawater samples.

Due to their antibacterial and antifungal properties, parabens are commonly used as biocides preservatives in food, cosmetics, pharmaceuticals. Parabens have been reported exist various water matrices at low concentrations, which renders the need for sample preparation before quantification using analytical techniques. Thus, methods such solid-phase extraction (SPE), rotating-disk sorptive (RDSE), vortex-assisted dispersive liquid-liquid (VA-DLLE) that preconcentration discussed. As a result of methods, techniques now detect trace levels ranging from µg/L ng/L. These compounds detected water, air, soil, human tissues. While full impact on health ecosystems is still being debated scientific community, it widely recognized can act endocrine disruptors. Furthermore, some studies suggested may carcinogenic effects. The presence environment primarily due wastewater discharges, widespread contamination concentrations increased during COVID-19 pandemic waves. Neglecting exposes humans these through contaminated food drinking water. Although there reviews focus occurrence, fate, behavior environment, they frequently overlook critical aspects removal policy development, regulatory frameworks. Addressing this gap, effective treatment relies combined approaches address both cost operational challenges. Membrane filtration nanofiltration (NF) reverse osmosis (RO), demonstrate high efficacy but hindered by maintenance energy costs extensive fouling. Innovations anti-fouling efficiency, coupled with pre-treatment like adsorption, help mitigate enhance scalability. combining adsorption advanced oxidation processes (AOPs) or biological treatments significantly improves economic efficiency. Integrating systems O₃/UV activated carbon, along byproduct recovery strategies, further advances circular economy goals minimizing waste resource use. This review provides thorough overview paraben monitoring wastewater, current techniques, policies govern presence. perspectives future investigations shaping aimed mitigating risks

Antibiotics, posing a major threat to life on earth and water causing propagation of antibiotic resistant bacteria mutant genes. Traces these toxins are found both in aquatic as well terrestrial ecosystem. Various techniques, that is, ozonation, membrane filtration, Fenton process, etc., applied for their removal but have many shortcomings, so adsorption is picked efficient, simple relatively safe technique. This review article discusses the classification antibiotics, effect unnecessary application methods remnants from sources. Also, compares adsorptive antibiotics remnant with other primitive advance suggesting one effective techniques.
