Degradation of 2,4-dichlorophenol contaminated soil by ultrasound-enhanced laccase

Mengjuan Zhuang et al.

Summary: In this study, ultrasound-enhanced laccase was successfully used to degrade 2,4-DCP in soil, achieving a degradation rate of up to 51.7%. The optimal pH for laccase degradation of 2,4-DCP increased when ultrasound was utilized, making the degradation technology more practical. Analysis from HPLC and GC-MS revealed the degradation pathway of 2,4-DCP in soil, showing that it gradually transformed into phenol through dechlorination before generating small molecular organic matter.

New insights into stoichiometric efficiency and synergistic mechanism of persulfate activation by zero-valent bimetal (Iron/Copper) for organic pollutant degradation

Liping Fang et al.

Summary: Extensive studies have been conducted on the catalytic efficiency of zero-valent iron-based bimetals with persulfate, but little is known about the stoichiometric efficiency, underlying mechanisms, and reaction centers of these catalysts. This study investigated nanoscale zero-valent Fe/Cu catalysts in decomposing 2,4-dichlorophenol, revealing that Cu is likely the predominant reaction center over Fe. The findings shed light on the stoichiometric efficiency and reaction centers of Fe/Cu catalysts in activating PS for pollutant removal.

Surfactant-enhanced remediation of oil-contaminated soil and groundwater: A review

Jian-Wu Liu et al.

Summary: Oil leakage during extraction, processing, transportation, and storage can seriously damage the soil and groundwater environment. Surfactants play a crucial role in enhancing the remediation of oil-contaminated sites by reducing surface tension, improving contact efficiency of contaminants, and suppressing tailing and rebound effects. Different types of surfactants offer diverse options for remediation, with biosurfactants and mixed surfactants being particularly effective and worth attention. Adsorption of surfactants on soils and aquifer sediments should be minimized to avoid decreased remediation efficiency and potential secondary pollution.
