Photocatalytic degradation of drug residues in water

摘要

At present about 3600 drugs for human and veterinary medicine are licensed in Germany. In 1997 nearly 45 tons of the lipid regulator bezafibrate or nearly 75 tons of the nonsteroidal anti-phlogistic and anti-inflammatory drug diclofenac were prescribed.rnDifferent ways and sources lead to the fate of drugs in the aquatic environment. Today about 150 drugs and their metabolites are detected in water of rivers and lakes. Most of the organic drugs are very stable and non biodegradable compounds. Regional and international studies showed the increase of drugs in water due to the incomplete removal of these substances during passage through a sewage treatment plant.
