Barium sulfate suspensions: an evaluation of available products

Gluten content of barium sulfate suspensions used for barium swallows in patients with celiac disease.

PURPOSE To determine the availability and accuracy of information provided by hospitals, imaging centers, and manufacturers regarding gluten in barium sulfate suspensions. METHODS A total of 105 facilities were contacted via telephone to determine the gluten content of the contrast media used in those facilities. Manufacturers were contacted and their Web sites reviewed to determine the glute...

Preparation of High-Purity Grade Ammonium Sulfate from Locally Available Products

Barium sulfate aspiration.

A woman was evaluated for dyspnea after she inhaled barium sulfate during an upper gastrointestinal barium study that was administered by means of a percutaneous endo scopic gastrostomy tube. A plain radiograph of the chest revealed alveolar barium sulfate depositions (arrows) in the middle lobe of the right lung and in the lower lobes and the posterior aspects of the upper lobes of both lungs ...

Evaluation of Barium Sulfate (Barite) Solubility Using Different Chelating Agents at a High Temperature

Barium sulfate (barite) is one of the widely used weighting materials in the preparation of drilling fluid for deep oil and gas wells. Barite is not soluble in the regular solvents; such as, hydrochloric acid (HCl) and other acids. Therefore, in this study, we focused on evaluating the dissolution of the industrial barite particles in different chelating agents. Chelating agents; such as, dieth...

Flotation of Barium Sulfate Contaminants Soils

Flotation is, doubtless, the most important process among the various techniques used for the treatment of ore. This generalpurpose technique allows the treatment of several complex ores (lead zinc, copper zinc), sulphides (copper, lead, and zinc), oxides (hematite, quartz), oxidized minerals (malachite, cerusite) and even non-metal ores (fluorite, phosphate, coal). Due to the flotation, it is ...
