  • THE DETERMINATION OF SULFUR AS BARIUM SULFATE

    by the case of barium sulfate precipitation in the presence of iron salts. He claimed that the quantity of iron sulfate oc­ cluded vvas proportional to the barium sulfate up to a definite limit of adhesion, after which an excess of iron had no effect. These conclusions are only partially substantiated by other in­ vestigators. Richards and Parker26
