Abstract
Chemical methods were evaluated for the treatment of 1, 4-dioxane in industrial process wastewaters. The compound was rapidly oxidized by a combination of hydrogen peroxide and ferrous iron, although the rate of organic carbon removal was considerably slower than the disappearance of 1,4-dioxane from solution. Chlorine oxidation at 75°C was also found to be highly effective. The rate of the reaction was greatest at pH 5.2, suggesting that hypochlorous acid was the preferred oxidant. 1,4-Dioxane appeared to be completely oxidized during chlorination, although the removal of organic carbon was somewhat slower than the disappearance of the parent compound.
