The application provides a nanocomposite, a nanocomposite phase material and a preparation method and application thereof, and the preparation method of the nanocomposite comprises the following steps: (1) mixing and reacting iron calcium phosphate ion oligomers and a polyvinyl alcohol solution to obtain a composite glue; and (2) mixing and reacting the composite glue obtained in the step (1) with a nanosheet dispersion solution to form a nanocomposite. The iron calcium phosphate ion oligomers and the polyvinyl alcohol are introduced into the nanosheet interlayer, in the evaporation self-assembly process, the ion oligomers are in-situ inorganic ion polymerization under the regulation of the polyvinyl alcohol molecular chain, an organic-inorganic interpenetrating homogeneous network is formed through hydrogen bond and coordination bond interaction in the nanosheet interlayer, and thus a firm 'organic-inorganic homogeneous network' structure is constructed between adjacent nanosheets. The nanocomposite prepared by the method has high tensile strength and toughness.

Methods, systems and devices for lowering a concentration of a PFAS in a solution including exposing a treatment solution to a UV light source from one or more lamps in a continuous reactor, the treatment solution comprising a PFAS, an inorganic ion, and having a pH of about 8 or more, and flowing the treatment solution through the continuous reactor at a flow rate of equal to or greater than 18.9 litres per minute (5 gallons per minute) while exposing the treatment solution to the UV light. The treatment solution to UV light in the continuous reactor results in partially or fully defluorinating about 80% or more of the PFAS in the treatment solution.

The application relates to a feldspar surface adsorption inorganic ion evaluation method based on a molecular dynamics simulation, characterized in that the evaluation method comprises the following steps: a feldspar surface model is constructed; water and inorganic ions are respectively inserted into the feldspar surface model to obtain a feldspar / water / inorganic ion model; molecular dynamics simulation is carried out on the feldspar / water / inorganic ion model; and the adsorption performance of the feldspar surface to the inorganic ions in water is evaluated according to the simulation result.
