The interaction of EDTA with barium sulfate - ScienceDirect
2007-12-15 · The aperture was 12 mm and 256 scans were obtained for all spectra. A small particle size (high surface area) barium sulfate was prepared at extremely high supersaturations by mixing BaCl 2 (0.5 M, pH 3) and Na 2 SO 4 (0.5 M, pH 3) with magnetic stirring. At this pH, agglomeration of the particles formed is avoided due to surface charge repulsion.
