When a radiopaque material is used for the single-scan method, it must be homogenous and uniform in appearance and must not create scatter. One such material isbarium sulfate, which is commonly used forgastrointestinal imaging. It is provided as a powder to be dissolved in water. When used ...
Barium ions from water soluble Ba salts (barium acetate, bariumchloride, bariumhydroxide, bariumoxide, bariumnitrate and barium(poly)sulfide) quickly precipitate in the presence of sulfate or carbonate ions (ATSDR, 2007), which illustrates that under natural conditions, Ba is effectively immobilized ...
After the reaction is carried out by adding ammonia water under stirring, the barium peroxide finished product is obtained by washing, suction filtration, drying and crushing at 110 ℃. Its BaCl2 + H2O2 +2NH3 · H2O → BaO2 + 2NH4Cl + 2H2O air oxidation method barium nitrate or barium ...
