Аннотация

Direct UV photolysis of the aqueous solutions of seven well-known pharmaceuticals was accomplished using a high-pressure mercury lamp. Within 30 min of irradiation, active substances of ranitidine and phthalylsulphathiazole were almost completely destructed, whereas paracetamol and novocaine were destroyed to a lesser extent. Stable organic products are not formed during the destruction of paracetamol, while the photolysis of sulphaguanidine leads to the formation of acetic acid, which was confirmed by means of 1H NMR spectroscopy. It is concluded that UV photolysis may be used for initial wastewater treatment to remove the studied micropollutants.
