The precipitation of gypsum, celestine, and barite and coprecipitation of radium during seawater evaporation

While the precipitation paths of the major ions (i.e., Ca2+, Na+, K+, Cl− and SO42−) during seawater evaporation have been extensively studied, the precipitation of minor solutes from evaporated seawater was not thoroughly studied. The present study aims to achieve a quantitative understanding of Sr2+, Ba2+ and Ra2+ removal from evaporated seawater, by exploring in-situ evaporation of seawater in a series of ponds of a salt plant.
