Abstract : The macro-volumetric method for sulfate determination in sea-waters has been adapted to the microanalysis of pore-waters. Each measurements needed of 2.0 ml samples which are exactly diluted with 20 ml of twice-distilled water. Cation interferences are avoided by passing the obtained solution through a small column filled with cation-exchange resins. The titration of the eluate sample, added with a suitable quantity of alcohol, is then carried out with a hydro-alcoholic solution of BaCl2 0.0052 M in presence of Thorin as indicator. (Author)
