Soils have a natural characteristic called the cation exchange capacity (CEC) that allows them to hold (and exchange) cations (e.g., Ca+2 or Na+). These cations are held tight enough on the CEC that ...

Saltwater intrusion from sea level rise and tidal flooding is increasing soil salinity risks in coastal farm fields (Figure 1). Soil salinity is related to the presence of soluble salts and cations ...

Conventional techniques for precipitating highly soluble salts (for brine reduction or elimination) typically require phase change of water via evaporation or freezing, which is energy intensive.

Barium (Ba) salts have a range of solubilities in water. Ba metal is insoluble in water but soluble in alcohol. The three least soluble Ba salts are the sulfate, the carbonate, and the sulfide. The ...
