  • Publication number: 20140301792
    Abstract: A method for controlling dust on a saline dry lakebed or similar environment enriched with sodium carbonate and sodium sulfate is disclosed comprising, the Interim Solution method that achieves resistance to windborne dust release. The Interim Solution is a dilute aqueous solution containing a divalent cation chloride salt and anionic polyacrylamide that can be applied to dust-emission prone lakebed surfaces by spraying or other means that achieves a relatively even application. The chemical reaction that occurs upon contact of the Interim Solution with the salts of the lakebed soil creates stable compounds that are interconnected by the long-chain molecules of the polyacrylamide that binds the molecules derived by the chemical reaction into a surface skin that protects against wind erosion. A salt byproduct, sodium chloride, remains soluble in the near surface soil will tend to seal the surface against evaporation.
