7.2 Measurement of barium sulfate turbidity: 7.2.1 Immediately after the stirring period has ended, pour solution into absorbance cell. 7.2.2 Measure turbidity at 30-sec intervals for 4 min. 7.2.3 Record the maximum reading obtained in the 4-min period. 7.3 Preparation of calibration curve: 7.3.1 Prepare calibration curve using standard sulfate

Method 375.2, Revision 2.0: Determination of Sulfate EPA

The sample containing sulfate is then reacted with an alcohol solution of barium chloride and methylthymol blue (MTB) at a pH of 2.5-3.0 to form barium sulfate. The combined solution is raised to a pH of 12.5-13.0 so that excess barium reacts with MTB. The uncomplexed MTB color is gray; if it is all chelated with barium, the color is blue.

Barium and Compounds CASRN 7440-39-3 DTXSID8023894

Jul 11, 2005 Under EPA's 1986 Guidelines for Carcinogen Risk Assessment, barium would be classified as Group D, not classifiable as to human carcinogenicity. Under the Proposed Guidelines for Carcinogenic Risk Assessment (U.S. EPA, 1996), barium is considered not likely to be carcinogenic to humans following oral exposure and its carcinogenic potential

Ecological Soil Screening Levels for Barium epa.gov

Particulate phase barium is expected to be physically removed from the air by wet and dry deposition. Soluble barium compounds, such as barium nitrate, barium cyanide, barium permanganate, and barium chloride, are expected to be mobile in the environment. Soluble barium can react with sulfates and carbonates in water forming insoluble barium

Barium sulfate Wikipedia

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4.It is a white crystalline solid that is odorless and insoluble in water.It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.
