Abstract
A study on the salt effect of the singlet molecular oxygen-mediated ph oto-oxidation of organic compounds was carried out. The photo-oxidatio n rates under different solvent conditions (water plus NaCl 0.45 M; me thanol and ethanol plus LiCl 0.45 M; seawater and distilled water) wer e compared. As a general trend the presence of salt reduces the veloci ty of photo-oxidation, Although solvent polarity certainly plays a com mon role in the photo-oxidation process, particular kinetic behaviours were obtained for the differing derivatives, The individual photo-oxi dation mechanism for each family of compounds must be saved for a furt her discussion.
