ASTM WK44300

    New Test Method for New Method for Determination of Total Nitrogen, Total Kjeldahl Nitrogen by Calculation and Total Phosphorus in Water and Waste Water by Ion Chromatography

    (What is a Work Item?)

    Developed by Subcommittee: D19.06 | Committee D19 | Contact Staff Manager



    WK44300

    1. Scope

    1.1 This test method is applicable for the analysis total nitrogen (organic nitrogen + ammonium + nitrate + nitrite) as nitrate and total phosphorus as orthophosphate in unfiltered water samples by alkaline persulfate digestion followed by ion chromatography. The analytical step is equivalent to ASTM D4327. 1.2 Total Kjeldahl nitrogen is determined by subtraction of an undigested sample from a digested sample. (see Summary of Test Methods)

    This standard is needed because it is a new, direct injection technique for the simultaneous determination of total nitrogen and total phosphorous.
