ABSTRACT:
Processes for controlling pollution by: (a) devolatizing vapor phase chemical pollutants (VP's) found in effluents and other bodies and streams of gases and liquids, and (b) stabilizing substrates from which the VP's are released. The offending VP's are converted to less offensive or inoffensive materials by interaction with an appropriately formulated treating agent (VTA/C) containing a primary halogen and at least one additional ingredient selected from the following classes of constituents (optional if bromine is the primary halogen and otherwise required): oligodynamically active metals, cohalogens, adjuncts, and facilitators. The major constituent(s) may be supplied as such, or a source of the constituent may be provided. Actinic radiation can be employed to promote reactions between the VP and the VTA/C, which is often formulated as an aqueous scrubbing medium. The VTA/C may, however, be employed in other ways--for example: (a) by gaseous infusion into a reaction zone; (b) by dusting or coating the treating agent onto, or otherwise directly adding it to, a substrate prone to evolve VP's to control the emission of VP's from the substrate; or (c) by impregnating it into an activated carbon carrier.
