ASTM WK51894

    New Test Methods for Anions in High Ionic Water by Ion Chromatography Using Tandem Suppressed Conductivity and Ultraviolet (UV) Detection

    (What is a Work Item?)

    Developed by Subcommittee: D19.05 | Committee D19 | Contact Staff Manager


    1. Scope

    1.1 This test method covers the simultaneous determination of fluoride, nitrite-N, ortho-phosphate-P, bromide, nitrate-N, and sulfate ions in high saline water (up to 20 % sodium chloride) by suppressed ion chromatography and tandem ultraviolet (UV) detection. 1.2 Units--The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    Currently, ASTM D4327 covers analysis of anions in various matrices. There is a great difficulty for low-level analysis of UV-sensitive analyte-like nitrite, bromide, and nitrate in the presence of very high levels of chloride concentrations (sea water, brine, and high ionic wastewater). This test method enables the user to analyze low-level concentrations of the above-mentioned UV-active analytes in the presence of high concentrations of chloride (up to 30 % sodium chloride solution). If this test method is successfully published, it may help the US EPA for regulatory purposes.
