文摘

Sulfamethoxazole, sulfadimethoxine, cimetidine and caffeine photodegradation rates were greater in effluent than river water. Compound photodegradation rates increased with increasing fraction of effluent in river water. Compound photodegradation reactions via 3OM* or 1O2 pathways were quenched by river water organic matter. Indirect photodegradation rate constants correlated with water optical properties (E2/E3).
