Ozone/hydrogen peroxide pretreatment of nonyl-phenol ethoxylates, ethylene oxide/propylene oxide block copolymers, and polypropylene glycol

摘要

The effectiveness of the ozone/hydrogen peroxide advanced oxidation process (AOP) on the biodegradability of selected nonylphenol ethoxylates (NPEs), ethylene oxide/propylene oxide (EO/PO) block coplymers, and polypropylene glycol (PPGs) was examined. The results showed that advanced oxidation was highly effective at enhancing the biodegadability of EO/POs and PPGs. Advanced oxidation was less effective at enhancing the biodegradability of the NPEs examined. Relationships between specific structural features of each class of compounds and their biogeradability were examined.
