Summary: This study investigated the hydrophobic behavior of metal ion-modified commercial acoustic melamine foam (MF) and evaluated its use as a sorbent. Secondary modifications with polydopamine (PDA) and 1-octadecanthiol (ODT) were carried out to prevent metal release and improve hydrophobicity. The modified MF (PNiMFO) formed a complex with Ni2+ and showed superhydrophobicity with a water contact angle of 164 degrees. Furthermore, PNiMFO exhibited high sorption capacity for oil and organic solvents and could be reused for multiple cycles without loss of performance.

Summary: The concentration of heavy metal ions in industrial wastewater, especially Cr6+ and Co2+ ions, has drastically increased in the past few decades, leading to adverse effects on human health. There is a need for a quick, simple, and cost-effective method to remove these ions, as existing methods are time-consuming, expensive, and require high technical skills. In this study, chitin was selected from shrimp waste as a natural material, and a fluorescent carbon dot/chitin nanocrystal (C-dot/ChNC) sorbent was synthesized for the simultaneous detection and removal of heavy metal ions from wastewater. C-dot/ChNC showed high selectivity and sensitivity to Cr6+ and Co2+ ions and exhibited high adsorption capacities for chromium(VI) and cobalt(II). These weakly adsorbed ions were easily removed during regeneration, indicating high cyclability. Therefore, C-dot/ChNC is a viable sorbent for heavy metal ion removal during wastewater treatment.

Summary: This paper established artificial neural network (ANN) models to predict the sorption capacity of heavy metal ions onto microplastics in global aquatic environments. The predicted sorption capacity was influenced by the initial concentration of heavy metal ions and the salinity in surrounding water. Aged microplastics had higher affinity to heavy metal ions than virgin microplastics, with larger microplastics showing less sorption of Cd, Pb, and Zn ions. The laboratory studies were found to provide useful information for projecting the sorption capacity of heavy metal ions onto microplastics in global aquatic environments.

Summary: This study investigated the effects and mechanisms of microplastics (MPs) on the sorption-desorption, bioaccessibility, and bioavailability of cadmium (Cd) in paddy soil. The experiments showed that MPs significantly reduced Cd sorption in soil by covering the soil active sites and interrupting formation of CdCO3 and Cd3P2 precipitates. This led to an increase in Cd bioaccessibility and bioavailability in soil. The findings provide new insights into the impacts of MPs on the fate and risk of heavy metals in agricultural soil.

Summary: A novel Chitosan-modified Mimosa pigra biochar (CMPBC) was found to have higher efficiency in removing hexavalent chromium (Cr(VI)) from aqueous systems compared to pristine biochar. The sorption of Cr(VI) was heavily dependent on pH, with the highest adsorption occurring at pH 3.0. The results suggest the potential use of CMPBC as an easily available, environmentally sustainable, and inexpensive sorbent for the decontamination of Cr(VI) from water.

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: 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: For the first time, red clay brick waste was used in the green synthesis of nanoscale zero-valent iron (nZVI) in combination with activated charcoal (ACh). The resulting nZVI@ACh composite was analyzed and characterized through various techniques. The composite material was then tested for phenol remediation and showed promising results. The study also included theoretical calculations to understand the adsorption mechanism. The findings suggest that the adsorption of phenol onto nZVI@ACh follows the Langmuir model and is driven by physical forces.

Summary: This study focused on the thermodynamics of fluoride adsorption on bone char regenerated with NaOH for water defluoridation. The results showed that 0.075 mol/L NaOH was effective in recuperating the defluoridation properties of bone char with a regeneration efficiency higher than 90% during five adsorption/desorption cycles. It was calculated that around 0.25-0.46 mmol/g hydroxyapatite ligand exchange sites of regenerated bone char samples could be involved in the fluoride adsorption.

Summary: This manuscript introduces new group contribution models for calculating the surface tension of organic acids, derived from the Jasper equation and the van der Waals principle of corresponding states. The impact of incorporating the critical point restriction on the performance of these models is analyzed. Experimental data of surface tension for various organic acids are used to compare and evaluate the performance of the group contribution models. The results show that the models have good accuracy in calculating the surface tension of polyfunctional and aliphatic organic acids, but face challenges in calculating the surface tension of aromatic and dicarboxylic acids. The incorporation of critical point restriction does not improve the performance of the models.
