A proposed EPA method for the determination of dissolved hexavalent chromium in drinking water, groundwater and industrial wastewater effluents was developed using existing ion chromatographic techniques. Two solid waste matrices were briefly investigated. Aqueous samples were passed through a 0.45-micron filter and the filtrate was either (1) left(More)

The U.S. Environmental Protection Agency (U.S. EPA) and the American Society for Testing and Materials (ASTM) conducted a joint collaborative study validating an ion chromatographic method for determination fo inorganic anions (U.S. EPA method 300.0A and the equivalent proposed revision to ASTM method D4327). This study was conducted to determine the mean(More)
In this paper the nature, the characteristics, and the potential applications of the optogalvanic effect are explored in a broad set of experiments. The optogalvanic effect was investigated, for the Ar, Ne, He, Ar +, He +, Cu and Na atoms and N2, H~, CO, CN, NH2, He2, and CuO molecules in recombination-limited hollow cathode plasmas, with the use of dye(More)
