文摘
- •
Hydroxyl radicals can be indirectly quantified by quantifying CH2O.
- •
The Hantzsch method using acetoacetanilide is used to determine CH2O.
- •
H2O2 negatively interferes with the detection of CH2O.
- •
Interference depends on [H2O2]0/[CH2O]0.
- •
Interference is caused by the coupled equilibria.
