Multiple linear regression showed that TOC, amorphous aluminum and iron oxides contents, anion exchange capacity, pH, and silt content, jointly explained about 53% of the variance in PFOS K_d in soils. Variable charge soils with net positive surface charges, and moderate to elevated TOC content, generally displayed enhanced PFOS sorption than in temperate or tropical soils with TOC as the only sorbent phase, especially at acidic pH ranges. For the first time, two artificial neural networks were developed to predict the measured PFOS K_d (R² = 0.80) in the soils. Overall, both TOC and surface charge characteristics of soils are important for describing PFOS sorption.]]> Thu 23 Jun 2022 14:06:17 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47848 Thu 02 Feb 2023 16:32:49 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33454 Fri 30 Aug 2019 09:37:45 AEST ]]>
