Claims
- 1. The method of detoxifying water containing residual toxic amounts of a biocidal quaternary ammonium salt that comprises adding thereto at least a neutralizing amount of an anionic substance, sufficient to provide 0.3 to 600 ppm thereof in the water, followed by discharge into a waste stream, the quaternary being thereby rendered inactive to aquatic life; said anionic substance being a member selected from the group consisting of sodium stearate, sodium dodecyl sulfate, dodecyl glycine, dodecyl amino ethyl glycine, sodium palmitate, sodium oleate, sodium linoleate, or sodium dioctyl sulfosuccinate.
- 2. Method according to claim 1 in which the quaternary is an n-alkyl dimethyl benzyl ammonium chloride, in which alkyl has 12-18 carbons, including mixes.
- 3. Method according to claim 2 in which the anionic monomer is sodium dioctyl sulfosuccinate.
- 4. Method according to claim 1 in which 0.2 to 500 ppm of the quaternary is present in the water.
