N2 - Speciation of several trace elements upon evaporative preconcentration of seawater has been studied. The elements have been grouped with respect to their concentration trends as a function of increasing brine mineralization: copper, uranium, and mercury show an almost monotonic increase with growth in salinity; aluminum, iron, and manganese (to a lesser extent, chromium, nickel, and cobalt) show a nonconservative behavior; lead, zinc, and silver show a well-defined nonconservative behavior; and cadmium almost completely leaves the aqueous phase when the salinity increases. The speciation of the specified elements in one solution of various mineralization has been found from thermodynamic simulation.
