Efficient reductive and oxidative decomposition of haloacetic acids by the vacuum-ultraviolet/sulfite system

Jing Zhang et al.

Summary: This study proposes a VUV/sulfite system for the elimination of haloacetic acids (HAAs). The in situ generated hydrated electron (eaq-) is responsible for the initial degradation and dechlorination of HAAs, while hydroxyl radicals (OH) are responsible for their mineralization. Increasing pH values and sulfite dosage enhance the degradation of HAAs, but the presence of certain anions and dissolved organic matter inhibits the removal.

Partitioning behavior and ecological risk of arsenic and antimony in the sediment-porewater profile system in the Three Gorges Reservoir, China

Li Gao et al.

Summary: Arsenic and antimony exhibited different partitioning behaviors in the sediment-porewater profile system in the tributaries of the Three Gorges Reservoir (TGR). Arsenic showed a lower sediment affinity and higher mobility compared to antimony. The different behaviors could be attributed to the chemical fractions of the trace metals and the pH value of the sediments. The understanding of the transport and fate of arsenic and antimony in the aquatic environment was enhanced through this study.

The groundwater arsenic contamination in the Bengal Basin-A review in brief

Arpan Sarkar et al.

Summary: The presence of arsenic in the groundwater of the densely-populated Bengal Basin has caused great misery for millions of people. The high levels of arsenic are primarily found in the shallow aquifers, where the redox conditions and biogeochemical activities allow the arsenic to be released from the grey sands. The deep aquifers generally have lower or no arsenic, and the infiltration of arsenic from the shallow aquifers is mainly caused by irrigation pumping.

Reductive Removal and Recovery of As(V) and As(III) from Strongly Acidic Wastewater by a UV/Formic Acid Process

Linghao Kong et al.

Summary: This study proposes a UV/formic acid process for the reductive removal and recovery of arsenic from strongly acidic wastewater. The results show that the HCOOH reduction reaction under UV irradiation can efficiently transform As(V) and As(III) in the wastewater into highly pure solid As(0). The study provides a theoretical foundation for the reductive removal of arsenic from acidic wastewater.

Photoinduced formation of persistent free radicals, hydrogen radicals, and hydroxyl radicals from catechol on atmospheric particulate matter

Linjun Qin et al.

Summary: Catechol is capable of producing environmentally persistent free radicals (EPFRs), with CaO, CuO, and Fe2O3 promoting their formation. Additionally, the photochemical reactions of catechol resulted in the discovery of hydroxyl free radicals, hydrogen free radicals, and superoxide anions, which have adverse effects on human health.

Sulfite Activation by Glucose-Derived Carbon Catalysts for As(III) Oxidation: The Role of Ketonic Functional Groups and Conductivity

Yu Zhang et al.

Summary: The study demonstrates the efficient activation of sulfite by carbon catalysts for the oxidation of As(III), resulting in the generation of oxysulfur radicals and ultimately conversion into SO4 center dot-. Factors affecting activation performance include conductivity and ketonic functional groups. In normoxia conditions, the efficiency of the sulfite/carbon system is enhanced due to the reversible transformation cycle occurring among C=O/C-O-center dot/C-OH triads.

Reductive degradation of perfluorooctanoic acid in complex water matrices by using the UV/sulfite process

Zhongfei Ren et al.

Summary: Hydrated electrons generated from the UV/sulfite process have proved to be effective in degrading PFOA in water, with higher pH conditions enhancing the degradation significantly. However, the presence of carbonate, nitrate, and humic acid can significantly inhibit the degradation of PFOA.

Removal of arsenic(III) via nanofiltration: contribution of organic matter interactions

Youssef-Amine Boussouga et al.

Summary: The study found that in nanofiltration technology, the retention of As(III) significantly increased as the pH increased from 9 to 12, while the impact of salinity on As(III) retention was minor. Among different organic matter types, only humic acid (HA) was able to significantly increase As(III) retention.

Efficient photochemical denitrification by UV/sulfite system: Mechanism and applications

Ling Tan et al.

Summary: A novel photochemical denitrification process was proposed to effectively reduce nitrate to N-2 with nearly 100% denitrification efficiency. Experimental and theoretical calculations confirmed hydrated electron (e(aq)(-)) as the main reactive species for rapid removal of nitrate and nitrite. The high dispersion of e(aq)(-) in water and the rapid reaction rate contributed to the high selectivity of N-2, making the process promising for practical wastewater treatment.
