Decomposition of residual hydroxylamine by hydrogen peroxide treatment

摘要

Decomposition of excess hydroxylamine is accomplished by bringing a hydroxylamine-containing wastewater stream into contact with hydrogen peroxide. Most preferably, the wastewater stream is at neutral pH (e.g., pH between 7-8) and at elevated temperature (e.g., at least about 90 DEG C) when brought into contact with hydrogen peroxide. The presence of ammonium ion (NH<+>) accelerates the decomposition of hydroxylamine in the wastewater stream.
