Sulfate is precipitated as barium sulfate in a hydrochloric acid medium by the addition of barium chloride. Cover and let stand on steam bath for 12 hours to precipitate all sulfate as barium sulfate. Filter, wash barium sulfate precipitate with hot water until Cl-free, dry, ignite over burner, and weigh.
Barium sulfate (chemical formula BaSO 4) powder is efficient as an X-ray absorber.It is added as a means of producing X-ray contrast, so that normally radiolucent (X-ray invisible) PEEK artifacts are rendered some visibility under X-ray inspection in vivo.
Gravimetric Sulfate Determination by Ulrich de la Camp and Oliver Seely DISCUSSION. A sample containing an alkali sulfate is dried, weighed and dissolved in dilute HCl. Barium chloride solution is added in excess to precipitate barium sulfate, and the precipitate is digested in the hot solution.
Pharmacopoeial Analysis of Barium Sulphate to USP 29 - Test Method Overview Accurate purity determinations are required at several stages of product manufacture, to ensure product safety and meet regulatory requirements.
Barium Sulfate in Medicine: Thanks to its lead-like ability to block X-rays, barium sulfate may be used in a procedure called a barium swallow. This procedure involves drinking about a cup and a half of a chalky mixture called "barium meal." X-rays are taken as the barium …
B(SMEWW). This method can also be used for the determination of sulfate in coarse aggregate. 1.2 Both the screening and analytical approaches use the reaction of water-dissolved barium and sulfate to form an insoluble white precipitate of barium sulfate. The concentration (turbidity) of the precipitate is proportional to the sulfate ...
3. Convert the mass of the barium sulfate precipitate, formed in each trial, to moles. 4. Use the moles of BaSO 4 from 3 above to calculate the molarity of the Ba(OH) 2 solution. 5. Compare the results of your calculations from 2 and 4 above with the actual molarity of the Ba(OH) 2 solution.
November 14, 2018 — Voyageur Minerals Ltd. signed a joint venture agreement with Chief Medical Supply Ltd (CM) of Calgary, Alberta to engage in the development, marketing and commercialization of human and animal radiographic contrast agents and related pharmaceutical products. The agreement will focus on development of barium sulfate contrast products.

and Berzelius, as early as 1829, claimed that barium sulfate, even when precipitated by an excess of barium chlorid from a solu tion of potassium sulfate, is always contaminated by the last salt. Rose3 states that the precipitate contains both potassium chlorid and barium chlorid even after thoroly washing with hydrochloric acid.

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its ...
Any treatment method that concentrates barium, as is the case with ion exchange softening, reverse osmosis, and distillation may cause precipitation. Barium sulfate will precipitate at concentrations of 2 ppm or greater. If the sulfate level in the raw water is greater than 2 ppm, barium sulfate …
