文摘
- •
Ozonation pathway of aqueous CTC solutions tested at pH 2.2 and 7.0.
- •
30 products detected and major ones arranged in production and degradation pattern.
- •
Confirmed structures of some products by NMR spectra.
- •
Math fitting by Matlab predicted the rate constants for major ozonation reactions.
- •
Ozonation at pH 2.2 changed the CTC structure while at pH 7.0 mineralized it.
