文摘
- •
Photocatalytic degradation of N-desmethyl, N,N-bidesmethyl and N-oxide-tramadol was studied.
- •
Degradation of all studied compounds was strongly inhibited in wastewater.
- •
Hydroxylation and oxidation are the main degradation pathways.
- •
HO• are the main reactive radicals during the photocatalytic process.
- •
A significant abatement of the overall toxicity was accomplished.
