Abstract
Six sediment and one seawater samples were collected from the Arabian Gulf. Seawater was modified to represent salinities from 35 to 70 ‰, sulfate from 2200 to 11500 mg 1−1 and carbonate from 600. to 4500 mg 1−1. The sediments were suspended in the modified seawater and spiked with 25 mg kg−1 of Al, Ba or Cu. Important complexes of Al, Ba and Cu in seawater were A1(OH)3°, A1(OH)4 −, BaCl2°, BaSO4°, Cu(OH)2° and CuCo3°. Salinity of seawater increased concentrations of Al, Ba and Cu. Seawater sulfate had no effect on the solubilities of these elements, however carbonate concentrations negatively influenced Ba solubility.This publication has 12 references indexed in Scilit:
