Abstract
A process is described for removing noxious compounds such as hydrocarbons which may or may not contain halogen and/or may or may not be aromatic, from solids (soil), water or gas, according to which process the solid, the water or the gas is treated with a complex of a transition metal and an alkaline polyamine in the presence of a peroxide. The complex is, for example, a complex of iron chloride and 1,4,7-trimethyl-1,4,7-triazonane. The peroxide is preferably electrochemically produced hydrogen peroxide.
Claims18
A process for removing noxious organic compounds from solids, water or gas containing at least one contaminant of the class of hydrocarbons, halogen-substituted hydrocarbons, nitro-substituted hydrocarbons and organic dyes, comprising the step of:
- treating the solid, the water or the gas with a complex of a transition metal, a peroxide and an alkaline polyamine which is substantially free from acid functional groups.
A process for removing noxious organic compounds from solids, water or gas containing at least one contaminant of the class of hydrocarbons, halogen-substituted hydrocarbons, nitro-substituted hydrocarbons and organic dyes, comprising the step of:
- treating the solid, the water or the gas with a complex of a transition metal, a peroxide and a 1,4,7-triazonane.
