Summary: This study evaluated the equilibrium and kinetics properties of CO2 adsorption on two RSS-derived AC samples. The Freundlich model accurately described the experimental results, indicating a heterogeneous phase for the adsorption process. The pseudo-second order model was found to be the most suitable for both blank and IL-functionalized AC.

Summary: Agricultural wastes, like date seeds, can be used to produce activated carbon for water/wastewater treatment. This study evaluated different types of date seeds and found variations in their physical-chemical properties. KOH impregnation was found to yield better results than H3PO4 impregnation. The Khalas seed type showed the highest adsorption capacity and promising potential compared to commercial activated carbon (CAC).

Summary: This study explored the use of Agave americana fibers for the preparation of activated carbon via chemical activation with phosphoric acid, and investigated the effects of preparation conditions on the adsorption capacity towards Alpacide Yellow. The optimal conditions for enhanced properties were found to be an impregnation ratio of 40 g/1 g, impregnation time of 6 h, and carbonization temperature of 400 degrees C. Despite its lower specific surface area compared to commercial activated carbon, the prepared activated carbon exhibited higher adsorption capacity due to the presence of pores and functional groups on its surface. The adsorption process followed a fractal kinetic model, while the adsorption isotherm model was stochastic.

Summary: In this study, AC obtained from apple peel was used to remove NR from aqueous solutions. The AC was characterized using BET, FTIR, XRD, and SEM/EDX analyses. Isotherm, kinetic, and thermodynamic parameters were determined and the Langmuir isotherm and PSO kinetic models showed the best fit to the experimental data. The removal percentage of NR dye reached up to 87.20% at 318 K. The research demonstrated the effectiveness of biomass-derived AC for wastewater treatment through adsorption technique.

Summary: A high-potential nanoadsorbent was synthesized and characterized for its efficiency in adsorbing triclosan (TCS) from aqueous solutions. The adsorption equilibrium was found to be influenced by the pH of the solution. The adsorption process followed a chemisorption technique, as evidenced by fitting the adsorption isotherm models to a Langmuir model. The synthesized MCNS adsorbent showed remarkable reusability and renderability, making it suitable for water filtration and industrial wastewater treatment.

Summary: Biochar has been proven to immobilize polycyclic aromatic hydrocarbons (PAH) and hetero-PAH in residually contaminated soils, and performs better than commercial activated carbon (AC). Steam-activated biochar (SABC) showed higher efficacy than AC, while pristine biochar (BC) had slightly lower performance but was still acceptable. Therefore, BC and SABC can be valid substitutes for AC in stabilizing residually contaminated soils.

Summary: This study used Monte Carlo simulations to analyze the effects of soil properties on the derivation of unified national soil screening levels (NSSLs). The results showed that NSSLs were insufficient in identifying contaminated sites in the south, central, and northwest regions, while they were too conservative in screening out sites that required no further action in the east and northeast regions. The findings of this study could contribute to more scientific and effective soil quality management in other large countries.

Summary: Pharmaceutical and personal care products (PPCPs) are commonly found emerging contaminants in groundwater, posing risks to drinking water safety and human health. This study investigated the occurrence and distribution of nine PPCPs in riverbank groundwater and adjacent rivers, finding variations in concentrations and major compounds depending on sampling locations and water systems. The spatial distribution of PPCPs in riverbank groundwater was influenced by hydraulic connection and aquifer lithology. Significant correlations were found between PPCP concentrations and physicochemical factors in groundwater. Overall, this study provides important evidence on the role of lithology and hydrological conditions in the composition, distribution, and influential factors of PPCPs in riverbank groundwater.

Summary: This paper proposes a multiphase partitioning equilibrium (MPE) model for predicting the distribution and vapor exposure risk assessment of volatile organic compounds (VOCs) in contaminated soil in arid areas. The study shows that soil moisture is a key factor controlling VOC partitioning, with vapor-solid interface adsorption dominating under low moisture conditions and adsorption into soil organic matter becoming the controlling factor as humidity increases.

Summary: Although many industrial heritage sites have been repurposed into attractive landscapes, the contamination and health risks from polycyclic aromatic hydrocarbons (PAHs) on industrial legacy surfaces remain unexplored. Through the collection of surface samples from buildings and facilities at Beijing coking plant, it was found that these surfaces were contaminated with carcinogenic PAHs, suggesting the need for regulation and remediation.

Summary: Traditional phase equilibrium models often over-or underestimate soil vapor concentrations for assessing VOC-contaminated sites. In this study, machine learning models were developed using soil-soil vapor data pairs collected from contaminated sites in northern China. The random forest (RF) model provides more accurate predictions of soil vapor concentrations compared to the classic dual equilibrium desorption model. Significant explanatory covariates affecting soil vapor concentrations include soil concentration and organic carbon-water partition coefficient. The findings contribute to more accurate risk assessments at VOC-contaminated sites.
