Bismuth subcarbonate

Bismuth subcarbonate [5892-10 ] (basic bismuth carbonate) is a white or pale yellow powder that is prepared by interaction of bismuth nitrate and a water-soluble carbonate. The exact composition of this dmg depends on the conditions of precipitation it corresponds approximately to the formula (Bi0)2C02. It has been widely used as an antacid (183).

Basic nitrate is usually found as an impurity in bismuth salts (e.g., bismuth subcarbonate), very often due to the mode of preparation from the metal via bismuth nitrate. 

Bismuth Subcarbonate To 0.25 g add 20 ml DW, 0.05 ml indigo-carmine and then, as a single addition but with caution, 30 ml sulphuric acid. Titrate with indigo-carmine until a stable blue colour is produced. The volume of indigo carmine required is not more than that equivalent to 1 mg of N03 (0.4%). 

Bismuth subcarbonate [(BiOl CO ] is used to make other bismuth compounds, cosmetics, enamel, and ceramic glazes. Its major use is as an opaque substance placed in the digestive tract to show up on X-rays. The bismuth blocks X-rays, and thus the physician can see patterns inside the stomach and intestines.

While in Europe most limit tests use the method of standard additions, the United States Pharmacopoeia [84] requires that an aliquot of the test element equal to the set limit be added to the sample. If the response of the sample solution is less than the difference between the sample solution and sample plus aliquot (control) solution, it passes the test. Such a test may be used to limit sodium in other alkali salts. Atomic absorption spectrometry using the air/acetylene flame has been shown to be sufficient to test lead contamination in bismuth subcarbonate [114] and in zinc oxide and carbonate [115]. Miller [88] has reviewed such applications.

Bismuth compounds are also widely used in various cosmetics. Bismuth oxychloride (BiOCl) is a lustrous white powder added to face powder. Bismuth subcarbonate [(Bi0)2C03] and bismuth subnitrate [4BiN03(0H)2 BiO(OH)] are also white powders used to give a pearl-like luster to lipstick, eyeshadow, and other cosmetics.

Bismuth Subnitrate. Bismuth subnitrate was the first contrast agent used clinically to visualize the alimentary tract (36). It was found to be toxic in humans through the reduction from nitrate to nitrite as a result, bismuth subcarbonate was substituted (82). When the toxic action was traced to the metal itself, the use of bismuth salts was discontinued. 

A few salts of bismuth such as bismuth subcarbonate, subgallate, subnitrate and subsalicylate or milk of bismuth, find use in the treatment of nonspecific diarrhea and for skin protectants [9]. However, their use in the chemotherapy of parasitic diseases is limited. The only noteworthy example is glycobiarsol (Id), an anhydride of a bismuth oxide and phenylarsonic acid, which has been found to be active against Entamoeba and Trichomonas spp. [8].

Magnesium trisUicate 5 g in 150 mL of water reduced the absorption of a single 100-g oral dose of nitrofurantoin in 6 healthy subjects by more than 50%. The time during which the concentration of nitrofurantoin in the urine was at, or above 32 micrograms/rtiL (a level stated to be the minimum inhibitory concentration) was also reduced. The amounts of nitrofurantoin adsorbed by other antacids in in vitro tests were as follows magnesium trisilicate and charcoal 99%, bismuth subcarbonate and talc 50 to 53%, kaolin 31%, magnesium oxide 27%, aluminium hydroxide 2.5% and calcium carbonate 0%. ...
