Thermal desorption as a high removal remediation technique

 · The high removal using thermal desorption can be compared to stabilization techniques where the leaching of PFASs to the aqueous phase can be reduced by >99% [59, 26], but comparably higher than using granulated activated carbon or anion exchange for PFAS removal in drinking water . Although soil stabilization techniques have shown high removal .

Adsorption and Desorption Characteristics of Pretilachlor

 · The desorption was found to be highest in the loamy sand soil followed by sandy loam and clay loam soil. The desorption percentage of Pretilachlor in three desorption cycles for different concentrations ranged 5.04 to 56.03 % in loamy sand, 3.14 to 23.12 % in sandy loam and 1.63 to 18.64 % in clay loam soil (Table 6).
