Abstract
The present invention relates to the use of a carbonaceous adsorbent for the removal of a recalcitrant compound (1,4-dioxane) from contaminated water. The adsorbent is able to reduce the concentration of 1,4-dioxane from thousands of μg/L to <3 μg/L (the current EPA guideline). In addition, the adsorbent is regenerable in place with low pressure steam.
