seawaterderived
Seawater-derived is a descriptor used in science and industry to refer to materials, chemicals, and energy products that originate from seawater. The designation highlights marine origin and distinguishes substances recovered from seawater brines or produced from seawater constituents from those derived from land-based resources. Seawater contains a wide array of dissolved ions and trace elements, including major ions such as sodium, chloride, magnesium, calcium, potassium, sulfate, and carbonate, as well as bromine, iodine, and lithium in varying concentrations.
Derivation typically involves separation and concentration steps. Traditional methods use evaporation ponds to concentrate salts and
Applications span food and industry (salt products and specialty salts), chemical manufacturing and pharmaceuticals (bromine and
Challenges include relatively low concentrations of some target elements, high energy and capital costs for separation,
