Abstract : Titration of sulfates by means of an aqueous alcoholic solution of BaCl2 using Thorin as indicator, has been adapted to sea-water analysis. Cationic interference has been eliminated by passing the sample, diluted with twice distilled water, through a cation-exchange resin column. Chloride interference has been compensated by standardizing the titrant solution with a solution of H2SO4 containing HCl at a concentration corresponding to the chlorinity of standard sea water. The SO4/Cl ratios of 41 samples collected in various areas of the Mediterranean Sea have been evaluated. (Author)
