ABSTRACT:
Methods for treating toxic chlorinated dibenzo-p-dioxin-contaminated media by photolytic degradation are disclosed. Soil contaminated wiht such toxins are contacted with a photolysis-activating agent such as 1-hexadecylpyridinium chloride and irradiated with UV radiation in the presence of one or more hydrogen donors.
