Summary for Patent: 5,645,374
Title: Method for dehalogenating contaminated water and soil
Abstract:A method for dehalogenating contaminated ground water and/or soil where the contaminated area is contacted with a titanium carboxylic acid derivative such as titanium oxalate, titanium citrate or titanium nitriloacetate and a corrin or porphyrin catalyst preferably vitamin B12 compound.
