Abstract:Na + , K + , Cs + and Ca 2+ are common exogenous cations that could be introduced into soils either via long-term tillage with inorganic fertilizers or the leakage of nuclear waste. However, the manner in which they co-adsorb and compete with the intrinsic potassium ions in illite, the response of intrinsic potassium (K 0+ ), as well as the underlying mechanisms of these interactions, remain unclear. These aspects were explored using molecular dynamics simulations based on a series of concentrations. Because o… Show more
“…Other studies have demonstrated that Na + ions preferred to anchor at the siloxane ring of illite which also contains a large number of negative charges. 67 An obvious sharp peak was also observed at each pH value in the RDFs of Na–OW (Fig. 7c), at a distance of 0.24 nm, due to the strong hydration energy of Na + .…”
The soluble inorganic carbon is an important component of soil carbon pool, and its fate in soils, sediments, and underground water environment has great effect on many physiochemical and geological...

“…Illite, a common layered aluminosilicate with a nanopore structure, is distributed widely in soils and has significant environmental implications (Yesilbas et al , 2019; Li et al , 2022). Its limited interlayer space leads to its large SSA, large CEC and good adsorption performance.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
