WebAn automatic colorimetric method for determining sulphate in natural water in the range of 5 to 400 mg per litre is presented. The method is based on the precipitation of barium sulphate and the release of the coloured acid chloranilate ion. A manifold has been developed for the determination of sulphate on the Technicon AutoAnalyzer. WebSep 28, 1998 · EPA estimates that about 3% of the public drinking water systems in the country may have sulfate levels of 250 mg/L or greater. The Safe Drinking Water Act (SDWA), as amended in 1996, directs the U.S. Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC) to jointly conduct a study to …
