Abstract
Elemental phosphorus in electrothermal phosphorus plant effluents is oxidized either by anodically produced atomic oxygen or by an anodically produced mixture of atomic chlorine and atomic oxygen. The elemental phosphorus content of the effluents may be lowered by use of this process from about 5 to 10 ppb to an undetectable level, i.e., below about 0.1 ppb.
