Summary: Temperature dependencies of adsorption equilibrium and kinetics of 2-, 3-, 4-nitrophenol by activated carbon were studied, showing an increase in adsorption rate and amount with rising temperature. Various models and equations were used for data analysis, and XPS technique was employed to study surface functional groups and adsorption mechanism, revealing weaker interactions of 2-nitrophenol molecules with carbon surface due to intramolecular hydrogen bonds.

Summary: In this study, an amino-rich coordination polymer Cu2I2(MA)2 was used for efficient adsorption and catalytic reduction of nitrophenols. The adsorption process followed the pseudo-second-order kinetic model and Langmuir isotherms model, with maximum adsorption capacities of 285.71, 232.02, and 131.57 mg g-1 for 4-NP, DNP, and TNP, respectively. The reduction reaction followed the pseudo-first-order kinetics, with kinetic rate constants of 0.4413, 0.3167, and 0.17538 min-1 for 4-NP, DNP, and TNP, respectively. The mechanism and factors affecting the adsorption and catalytic reduction were also studied.

Summary: The traditional belief about pore structure determining encapsulation ratio in substrate was challenged in this study, which demonstrated that surface adsorption also played a significant role. By encapsulating polyethylene glycol (PEG) within hydroxyapatite (HAP) and dickite substrates, it was found that HAP adsorbed PEG through the surface, affecting the direct impregnation process and leading to a calculated maximum encapsulation ratio close to the actual value.

Summary: This study investigates the importance of the interaction and position of the nitro group in the adsorption of 2-nitrophenol (2-NP), 4-nitrophenol (4-NP), and phenol by demineralized kraft lignin activated carbon (DKLAAC). The results show that the adsorption follows the order 2-NP > 4-NP > phenol, and both solubility and donor-acceptor complex mechanism play a significant role in the adsorption process. The experimental data fits well with the Langmuir adsorption isotherm and pseudo-second order kinetic models. The temperature study reveals that the adsorption process is endothermic and spontaneous with high affinity between DKLAAC and phenols.

Summary: The availability of pure and fresh water is crucial for human survival. With the increasing rate of water pollution, scientists are exploring methods to minimize its impact. The synthesis of a ternary PEG capped polyaniline/TiO2/CuO composite with a high surface area and its adsorption studies using Rhodamine B have been conducted. The composite showed efficient adsorption properties, following the Langmuir adsorption isotherm and pseudo second order kinetics. Thermodynamic studies indicated a spontaneous and exothermic process at lower temperatures. The findings highlight the effectiveness of the synthesized adsorbent for environmental remediation studies.

Summary: Chitosan (CS)/carboxymethyl cellulose (CMC) porous hydrogels crosslinked by epichlorohydrin and with polyethylene glycol (PEG) as a pore-forming agent were synthesized for removal of anionic (Congo red, CR) and cationic (methylene blue, MB) dyes from aqueous solutions. The addition of PEG significantly increased the adsorption of CR and MB, with optimal performance observed for hydrogels prepared with 2% CS and 2% CMC (CS2/CMC2). The adsorption processes followed pseudosecond-order and pseudo-first-order kinetics models for CR and MB, respectively. Freundlich and Langmuir models were suitable for describing the adsorption isotherms of CR and MB, respectively. The thermodynamic study confirmed that the adsorption of CR and MB by the hydrogels was spontaneous, with CR adsorption being endothermic and MB adsorption being exothermic.

Summary: The rapid and effective removal of pharmaceutical contaminants (PhCs) from water through adsorption is a big challenge due to the properties of most PhCs. Adsorptive membranes have advantages over conventional adsorbents for PhCs removal. This study developed PEG-coupled ionic grafting adsorption membranes with outstanding adsorption and antifouling performance for PhCs removal. The study provides a new design strategy for effective removal of PhCs from contaminated water using adsorptive membrane technique.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
