barium sulfate precipitate

Barium - Wikipedia

Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal cause of its high chemical reactivity, barium is never found in nature as a free element.. The most common minerals of barium are baryte (barium sulfate, BaSO 4) and witherite (barium carbonate, BaCO 3), both insoluble in water.

Sulfate Removal Technologies A Review - Water Online

Jan 06, 2015· 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 and ...

Barium chloride - Wikipedia

Its solutions react with sulfate ion to produce a thick white precipitate of barium sulfate. Ba 2+ + SO 4 2− → BaSO 4. Oxalate effects a similar reaction: Ba 2+ + C 2 O 4 2− → BaC 2 O 4. When it is mixed with sodium hydroxide, it gives the dihydroxide, which is moderately soluble in water. Preparation

Barium carbonate - Wikipedia

Barium carbonate reacts with acids such as hydrochloric acid to form soluble barium salts, such as barium chloride: BaCO 3 + 2 HCl → BaCl 2 + CO 2 + H 2 O. Pyrolysis of barium carbonate gives barium oxide. Uses. It is mainly used to remove sulfate impurities from feedstock of the chlor-alkali process. Otherwise it is a common precursor to ...

Sulfate - Hach Company

Sulfate ions in the sample react with barium in the SulfaVer 4 Reagent and form a precipitate of barium sulfate. The amount of turbidity formed is proportional to the sulfate concentration. The measurement wavelength is 450 nm for spectrophotometers or 520 nm for …

barium | Uses, Compounds, & Facts | Britannica

All soluble barium compounds are toxic to mammals, probably by interfering with the functioning of potassium ion channels. Barium sulfate (BaSO 4) is a white, heavy insoluble powder that occurs in nature as the mineral barite. Almost 80 percent of world consumption of barium sulfate …

Synonym: 2-Cyanoethyl phosphate barium salt hydrate, 3-(Phosphonooxy)propanenitrile barium salt hydrate Linear Formula: NCCH 2 CH 2 OPO 3 Ba · xH 2 O Molecular Weight: 286.37 (anhydrous basis)

Barium Chloride (BaCl2) - Structure, Properties, Uses, and ...

It is also called Barium Muriate or Barium dichloride. It is a white solid which is water-soluble, hygroscopic and gives a slight yellow-green colour to a flame. The chemical formula of Barium Chloride is BaCl 2. Barium salts are extensively used in the industry. The sulfate is used in white paints, particularly for outside use.

The absorption of specific barium salt anions /was examined/ in male Sprague-Dawley rats administered radiolabelled barium chloride, sulfate, or carbonate to fasted (24 hr) and non-fasted rats /strain not given/ by gastric intubation. Animals were saced from 2 to 480 min after administration and blood concentrations were measured.

Y. Nonomura, in Cosmetic Science and Technology, 2017 14.2.1.1.5 Barium Sulfate. Barium sulfate, BaSO 4, is made by reacting barium hydroxide and other barium sources with sulfuric acid and has a long history as a translucent white pigment.Barium sulfate can be formed in various shapes such as planar, starred, or spherical structures depending on the formulation condition, especially the ...

Dilution Magnesium Sulfate - GlobalRPH

Sep 03, 2017· In the presence of severe renal insufficiency, the maximum dosage of magnesium sulfate is 20 grams/48 hours and frequent serum magnesium concentrations must be obtained. Other Uses In counteracting the muscle-stimulating effects of barium poisoning, the usual dose of magnesium sulfate is 1 to 2 g given I.V.
