Summary: A novel uracil-modified chitosan (UCs) adsorbent has been successfully synthesized and its structure and adsorption performance have been studied. The results show that the adsorption capacity of UCs for anionic Congo Red dye is related to factors such as solution pH, dye concentration, and temperature. The adsorption process follows pseudo-second order and Elovich models, and involves multiple steps. The isotherm analysis indicates that the adsorption of CR dye by UCs follows the Langmuir model, suggesting monolayer adsorption. Thermodynamic analysis shows that the adsorption process is endothermic and leads to increased randomness in the system.

Summary: This study investigated the characteristics of activated carbon from cashew nut shell produced by potassium hydroxide activation at 600 degrees C in an N2 atmosphere. The sample obtained with a CNS/KOH ratio of 1:1 had the highest surface area compared to other ratio samples. The effects of contact time, pH, adsorbent dose, and initial dye concentration on brilliant green (BG) removal efficiency were studied using the CNS/KOH ratio of 1:1 sample as the adsorbent. The Langmuir isotherm provided the best fit for the experimental equilibrium data, with a maximum BG adsorption capacity of 243.90 mg/g.

Summary: In this study, high-performance adsorbents were developed by modifying chitosan with polyethylene glycol and formaldehyde. The adsorption behavior of the prepared chitosan beads in Reactive Red 2 dye wastewater was investigated, and it was found that the adsorption equilibrium followed the Langmuir model and pseudo-second-order kinetic model. The PEGylated chitosan beads showed a high adsorption capacity, attributed to the protonation of NH3+ groups on the surface and the enriched pore structure. HCl solution was effective for the regeneration of the beads, and their swelling behavior was pH-dependent.

Summary: This study investigates the impact of molecular aggregation on the multicomponent adsorption of three non-steroidal anti-inflammatory drugs (acetaminophen, diclofenac, and naproxen) on bone char from aqueous solutions through theoretical calculations and experimental results. The molecular properties of single compounds and their aggregates were used to explain the steric factors involved in the adsorption mechanism. The results show that the molecular properties of dimers and trimers of these adsorbates play a relevant role in multicomponent adsorption.

Summary: In this study, pilot-scale tests were conducted on a new design of Y-type corrugated polylactic acid (PLA) packing produced by a one-step 3D foam-printing process. Experimental tests showed that the FT.Y packing exhibited comparable or superior performance to the benchmark commercial Mellapak 250Y packing in terms of pressure drops and mass transfer coefficients. The FT.Y packing also demonstrated higher desulfurization efficiencies in wet Flue Gas Desulfurization than the benchmark packing. Overall, the 3D foam-printed FT.Y packing shows great potential in process intensification for absorption and distillation processes.

Summary: Wet Oxidative Scrubbing (WOS) is a process that can simultaneously remove SO2, NOx, and other pollutants from exhaust gases. It is gaining attention for its high efficiency, compactness, and reduced chemical usage. However, the application of WOS requires proper treatment of washwater, which has been investigated in this work using a washwater treatment process called R-PCF. The experiments show that R-PCF is effective in reducing the concentration of chlorine species, making it a valuable technique for washwater cleaning in WOS processes.

Summary: The paper presents experimental and theoretical research on the adsorption of paracetamol (PCM) and ibuprofen (IBP) on a new activated carbon derived from Erythrina speciosa tree pods. The adsorbent exhibits excellent porous properties with a BET surface area of 795.1 m2/g and an average pore volume of 0.422 cm3 g-1. The adsorption tests show that the maximum adsorption capacity of both IBP and PCM is achieved at pH = 3, where the adsorbate molecules are in their neutral form. The theoretical analysis suggests that both IBP and PCM are adsorbed through a multi-molecular mechanism on the surface of the adsorbent.

Summary: This study analyzes the thermodynamics and interfacial interactions of fluoride and arsenate adsorption on MIL-100(Fe) and MIL-101(Fe) structures. Experimental equilibrium studies show that fluoride adsorption is exothermic, while arsenate adsorption is endothermic. Density functional theory calculations indicate that arsenate adsorption is governed by ion exchange mechanism involving Fe centers, while electrostatic interactions affect fluoride adsorption on these metal-organic structures. MIL-101(Fe) exhibits superior adsorption properties for both fluoride and arsenate compared to MIL-100(Fe). MIL-101(Fe) shows outstanding performance for arsenate removal with high adsorption capacities. This study contributes to the understanding of MIL-family MOFs' adsorption properties, aiming to consolidate their utilization in water purification.

Summary: This study investigated the lipid composition of primary sludge from an urban wastewater treatment plant in Aguascalientes, Mexico. The study assessed the potential of the sludge as a raw material for biodiesel production. Lipid recovery was achieved through solvent extraction, with different solvents used for dry and dewatered sludge. The results showed that the physicochemical characteristics of the sludge, which were influenced by seasonal changes and population activities, affected the lipid recovery rate. These factors should be considered when designing large-scale extraction equipment for biofuel production.

Summary: This study investigates the decomposition of Acid Orange 10 dye using the H2O2/IO4- reactive system and evaluates the impact of various factors on the process efficiency. It found that the concentrations of H2O2 and IO4- exert a nonmonotonic effect on the removal of AO10, and acidic conditions significantly promote the degradation efficiency. Moreover, an increase in salinity decreases the effectiveness of AO10 removal.

Summary: This research explores the effect of tetraethyl orthosilicate (TEOS) on the interaction mechanism in the hybrid polyvinyl alcohol (PVA)/graphene oxide (GO) material. The addition of TEOS significantly reduces the crystallinity of PVA and improves the thermal stability of PVA/GO. Theoretical simulations suggest that the bonding interaction energies are enhanced by the addition of SiO2, and the compatibility between PVA and GO is increased with the presence of SiO2.

Summary: This study investigates the adsorption of basic blue 3 and reactive blue 19 dyes using biomass wastes of sugarcane bagasse and coconut endocarp. The adsorbent-adsorbate interactions were analyzed using DFT calculations and Response Surface Models (RSM). Results showed that the optimal conditions for removing BB3 dye were 40 degrees C and pH 4, while RB19 dye adsorption had the best conditions at 40 degrees C and pH 6. RSM models satisfactorily correlated the experimental data with high R2 values and low modeling errors. DFT calculations revealed the specific interactions between the dye molecules and the natural polymers of the lignocellulosic materials.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
