Abstract
A process for treating an aqueous waste water or groundwater containing organic contaminants degradable by hydrated electrons comprises contacting the aqueous waste water or groundwater with an agent which generates hydrated electrons on photolysis. Additionally, the aqueous waste water or groundwater is irradiated with UV light to photolyse the hydrated electron generating agent, thereby generating hydrated electrons to degrade the contaminants. In one embodiment, the aqueous waste water or groundwater is contacted with the hydrated electron generating agent and a reducing agent to recycle the hydrated electron generating agent.
