Natural soil mineral nanoparticles are novel sorbents for pentachlorophenol and phenanthrene removal

Thermal assisted heterogeneous activation of peroxymonosulfate by activated carbon to degrade perfluorooctanoic acid in soil

“…Soil is what links the atmosphere and the hydrosphere, and holds a major role in the conversion and build-up of contaminants in both land-based and aquatic environments. The effective and timely removal of soil pollutants can prevent their penetration into groundwater, stop their release into the atmosphere, and/or minimize the dangerous threat they pose to the safety of living organisms [He et al, 2015.Although a good deal of studies to date have been conducted to explore and strengthen the removal of PFOA in aqueous media [Yang et al, 2021, Turner et al, 2019, however only a few approaches have been developed for the degradation of PFOA in soil , Sammut et al, 2019, Turner et al, 2021.…”

Mineralization of pentachlorophenol by ferrioxalate-assisted solar photo-Fenton process at mild pH

“…The solubility of PCP, with pKa = 4.75 (He et al, 2015;Guemiza et al, 2017), is highly dependent on pH, being low at pH < 5.0 (≤ 14 mg/L) but very high at pH > 6.0 (> 100 mg/L) since its anionic form is predominant. As a result, it has been detected in industrial wastewater of pH 9.0 at a concentration of 490 mg/L (Rahmani et al, 2018).…”
