Barium-sulfate contrast materials that are administered by enema (rectally) are used to enhance standard x-ray, fluoroscopy, and CT images of the lower gastrointestinal (GI) tract (colon and rectum). In some situations, iodine-based contrast materials are substituted for barium-sulfate contrast materials for rectal administration.
Barium is sometimes found naturally in drinking water and food.

In the case of sulfates, one can add barium chloride to precipitate barium sulfate. Barium chloride is not cheap, but if the need is seasonal, this method may save on capital costs and prevent the need for brine management. This method will also increase chlorides in the discharge, on a molar equivalent basis to sulfates in the inlet. ...

Barium sulfate (BaSO 4) is a chemically inert, insoluble mineral. It can only be liquified as a suspension, with the help of emulsifiers, stabilizers, dispersants, laxatives, sweeteners, thickeners and preservatives. (Plant gum [e.g., acacia, tragacanth] is added when mucosal coating is desired.
locations. Pure barium sulfate has a specific gravity of 4.50 g/cm3, but drilling-grade barite is expected to have a specific gravity of at least 4.20 g/cm3 to meet API specifications. …
Uses for barium sulfate. Barium sulfate is used to help diagnose or find problems in the esophagus, stomach, and bowels. It is a radiographic contrast agent. Contrast agents are used to create a clear picture of the different parts of the body. Barium sulfate is to be given only by or under the direct supervision of a doctor.
To improve the stability of the barium sulfate suspension, different stabilizing agents, including thymol and gelatin, tween80 (polysorbate 80), and polyvinyl ...

Mp: 1580°C (with decomposition). Density: 4.25 -4.5 g cm-3. Insoluble in water, dilute acids, alcohol. Soluble in hot concentrated sulfuric acid. Used as a weighting mud in oil-drilling, in paints, paper coatings, linoleum, textiles, rubber. Administered internally ("barium cocktail") as a radio-opaque diagnostic aid.
Serious side effects of the test are rare, but report an unexplained fever, blood in the stool, or significant abdominal pain promptly. After the test, drink plenty of water to help avoid constipation and to help flush the barium out. You may have light or white stools for a few days after the test.
If sulfate must be further reduced ("polished"), an add-on process such as barium, CESR, or SAVMIN is recommended. As a polishing step for sulfate removal, barium salts can be added to precipitate barium sulfate, which has a very low solubility in water, with the final sulfate concentration limited only by the amount of barium added …
You may be advised to drink plenty of fluids and eat foods high in fiber to expel the barium from the body. You may also be given a cathartic or laxative to help expel the barium.
