Description:
The report gives results of several analytical procedures for separating and detecting non-extractable water-soluble organic material, including low molecular weight acids, alcohols, ketones, and other categories of compounds. (There are many ways to analyze hydrophobic extractable organics, but few for hydrophilic materials.) An analytical scheme has been developed that utilizes several chromatographic procedures standards with known water-soluble compounds from a variety of compound categories. The precision and accuracy data for each compound analyzed using these chromatographic systems are reported. Additional areas described in the report include: (1) the application of total organic carbon/freeze drying to monitor and concentrate non-extractable water-soluble alcohols from water; (2) the detection of specific compound categories using colorimetric procedures such as the Anthrone and Molisch tests; (3) the application of Level 1 procedures using water-soluble model compounds; (4) the evaluation of gas chromatography/Fourier transformation infrared as a viable way to analyze hydrophilic materials in fractions obtained from the Level 1 fractionation scheme; and (5) an analytical way to detect linear alkylbenzene sulfonates.
