Summary: The sulfidation of nanoscale zerovalent iron (S-nZVI) enhances the degradation efficiency of various chlorinated hydrocarbons (CHCs) in groundwater, with the most significant improvement observed for chlorinated ethenes. Under electron limited conditions, S-nZVI enables either higher or comparable maximum degradation quantity for all CHCs investigated, indicating its promise for remediating groundwater contaminated by CHC mixtures. Sulfidation suppresses the generation of partially dechlorinated products and favors degradation pathways leading to non-chlorinated benign products, providing valuable insight for the assessment of S-nZVI applicability and benefits in CHC remediation.

Summary: Improper discharge and management of agro-forest byproducts escalate global warming and water/air pollution, while their conversion into smart materials presents a promising strategy for waste management. Activated carbons (ACs) with developed porous structure and surface functional groups are extensively used as adsorbents, and their adsorption capacity can be enhanced through surface modifications for specific applications.

Summary: The presence of polycyclic aromatic hydrocarbons (PAHs) in groundwater poses a significant threat to human health worldwide, with Fenton oxidation processes showing promising results in removing naphthalene (NaP). Among different oxidants, hydrogen peroxide (H2O2) proved to be the most effective in degrading NaP. Additionally, the inhibitory effects of weak alkaline pH and HCO3- in actual groundwater can be counteracted by increasing dosages of oxidants and Fe(II).

Summary: Biochars have been shown to effectively reduce PFAS leaching in contaminated soils. This study produced and tested eight different waste timber biochars, with varying activation levels and production methods. The results suggest that the sorption capacity of biochars is influenced by activation degree, temperature, and soil organic carbon content.

Summary: The study investigates the use of carbon-based materials to activate peracetic acid (PAA) in the repair of groundwater, focusing on the degradation of sulfamethoxazole (SMX) using thermally modified activated carbon (AC600). The research examines the influence of groundwater pH, chloride ion (Cl-), bicarbonate (HCO3-), sulfate ion (SO42-) and natural organic matter (NOM) on the SMX removal process. The findings demonstrate that AC600 effectively activates PAA, and increasing doses of AC600 and PAA enhance the SMX removal, with bicarbonate inhibiting the process and chloride ion promoting it.

Summary: This study investigated the use of a nonpumping reactive wells (NPRWs) system with a mixture of granular activated carbon (GAC) and microscale zero-valent iron (MZVI) for the treatment of nitrate-contaminated groundwater. Batch experiments were conducted to determine the reduction kinetics of nitrate and phosphate in water. The results showed that the GAC-based NPRWs achieved a 0.6% g(-1) reduction rate for nitrate, while the mixed MZVI/GAC achieved a higher efficiency of 5.5% g(-1). The use of mixed MZVI/GAC in NPRWs resulted in minimal changes in pH and EC of the groundwater outflows.

Summary: A new adsorbent material was prepared by coating activated carbon with hydrothermal carbon derived from sucrose. The material exhibited different properties from the combination of the activated carbon and hydrothermal carbon, indicating the formation of a new material. It had a high specific surface area (1051.9 m(2) g(-1)) and slightly higher acidity than the starting activated carbon (p.z.c.-point of zero charge 8.71 vs. 9.09). The adsorption properties of a commercial carbon (Norit RX-3 Extra) were enhanced across a wide pH and temperature range. The monolayer capacity values according to Langmuir's model reached 588 mg g(-1) for the commercial product and 769 mg g(-1) for the new adsorbent.

Summary: The study demonstrates that persulfate oxidation has the potential to convert total PFASs in impacted soils into simpler and more recoverable PFAAs, leading to higher leaching rates of total PFASs. Additionally, after persulfate treatment, the remaining PFAS precursors in the soil were mostly cationic and zwitterionic substances. Treating soils with persulfate may be an effective remediation technique.

Summary: The study focuses on the effects of green processes in hybrid PDMS membranes on CO2 separation. It is found that controlling reaction time can help in fabricating symmetric membranes with a uniform and dense selective layer. A higher TEOS concentration decreases reaction time and allows for a fully crosslinked structure, leading to more efficient CO2/N2 separation. Additionally, membranes prepared at a high curing temperature of 120 degrees C showed improved separation performance, with excellent CO2 permeance and selectivity.
