Abstract
Recently, 1,4-Dioxane is known as the contaminant in water plants in Korea. Owing to its toxicity and potential health effect, 1,4-Dioxane must be determined at very low levels in drinking water. Studies on the removal of 1,4-Dioxane in drinking water were performed by using multi filtration system with activated carbons and membrane filter. For extraction of 1,4-Dioxane, methyl-t-butyl ether (MTBE) was used and then analyzed using gas chromatography-mass selective detection (GC/MSD). Removal experiment was proceeded for 300 L with a sample volume of 30 L. At first. The removal was 70%, 95% and 100% after using activated carbon, membrane and second activated carbon respectively. At larger accumulated water fluxes, the removal rate decreased at each filter. After the flow volume was 300 L, the removal rate was 30%, 88% and 99% through the first activated carbon, membrane and second activated carbon respectively.
