Hypochlorite destruction using urea |
摘要 |
A process for destroying waste alkali metal hypochlorite such as sodium hypochlorite is disclosed. The process involves reacting 50-90% and preferably 70-90% of the alkali metal hypochlorite with urea at from 20 DEG -60 DEG C. and pH 6-8 with pH 7-8 being preferred. The remaining alkali metal hypochlorite can be destroyed with a reactant such as sulfur dioxide, sodium sulfite, or sodium thiosulfate.
