Clay mineral dependent desorption of pyrene from soils by single and mixed anionic–nonionic surfactants

Desorption Kinetics of Heavy Metals (Lead, Zinc, and Nickel) Coexisted with Phenanthrene from a Natural High Buffering Soil

“…This may affect the kinetic modeling of multiple contaminants such as PAHs, over the entire contact time. That is why some previous researchers reported a two phase desorption kinetics of desorption [37,40]. The majority of Pb probably exist in available forms (exchangeable and carbonate fraction) [41].…”

Cosolubilization synergism occurrence in codesorption of PAH mixtures during surfactant-enhanced remediation of contaminated soil

“…Moreover, pertaining to the clay mineral composition, montmorillonite had stronger adsorption ability to nonionic surfactant such as Triton X-100 (TX100) than kaolinite (S anchez-Martín et al, 2008). We observed that soil samples collected in Guangzhou showed low adsorption capacity towards TX100 (Wei et al, 2015), which might be due to that the main clay composition of soil in Pearl River Delta is kaolinite (Liu et al, 2012b). However, the influence of SOM on the adsorption of TX100 onto soil in Pearl River Delta remains yet to be studied.…”

Ferrocene in agriculture: from agrochemicals and soil remediation to selective chemosensors

“…For the remediation of contaminated soils, the application of surfactants is gaining importance [47][48][49][50][51]. Ferrocenebased surfactants have the advantage to act both as surfactants and as redox-active compounds.…”
