Remediation of trichloroethylene contaminated soil by unactivated peroxymonosulfate: Implication on selected soil characteristics

Green synthesis trends and potential applications of bimetallic nanoparticles towards the sustainable development goals 2030

“…TCE is an organic compound with low water solubility and one of the most widely chlorinated hydrocarbons used in industry. 113 From its whole annual production, it is estimated that 83.60% of the TCE's annual production volume is used as an intermediate in the manufacture of hydrofluorocarbon HFC-134a, 114 which is primarily used as a refrigerant for domestic refrigeration and automobile air conditioners. 114,115 TCE's low solubility and high absorbance by soil organic matter (SOM) may produce a water/soil distribution, leading to environmental contamination with human health implications.…”

Controlled-Release Materials for Remediation of Trichloroethylene Contamination in Groundwater

“…TCE contamination sources fall into two primary categories: point source, i.e., a single, identifiable source of pollution that can be traced back to a specific location, and non-point source, i.e., more diffuse, multiple, and dispersed sources for which it is challenging to pinpoint the exact origin of contamination. Non-point source pollution, characterized by diffuse and challenging-to-monitor emissions, silently infiltrates environments, posing imperceptible exposure risks [15][16][17]. Due to the limited self-regulation capacity of ecosystems, achieving harmless levels of TCE in groundwater through natural degradation alone would require an extended timeframe.…”

Role of Borate Buffer in Organic Degradation by Peroxymonosulfate in the Presence of Metal Oxides

“…Among the sulfate radical-based AOPs, PMS oxidants have been actively utilized for in situ subsurface remediation owing to their high solubility and reactivity, decent stability, and sustainability [9][10][11][12][13]. PMS can be activated by external energy (e.g., heat, UV radiation, and ultrasound) [9], chemicals [14][15][16], transition metals [17], and carbonbased catalysts [18,19] to produce free sulfate and/or hydroxyl radicals; these radicals are highly reactive toward most organic compounds such as acids, alcohols, aldehyde, aromatics, amines, ethers, and ketones [20][21][22].…”
