Abstract
A headspace gas chromatographic mass spectrometric assay method was developed for determining 1,4-dioxane in water. A 5-mL water sample was placed in a 10-mL headspace vial and saturated with NaCl, and the solution was spiked with 1,4-dioxane-d 8 as an internal standard and sealed with a cap. The vial was heated in a headspace for 30 min at 90 °C. The method detection limit of the assay was 0.02 μg L−1 for 1,4-dioxane, and the relative standard deviations were less than 3%. 1,4-Dioxane was detected in the concentration range of 0.05–2.4 μg L−1 in 20 raw water. The developed method may be valuable for monitoring 1,4-dioxane in water.
