Electrochemical oxidation of drug residues in water by the example of tetracycline, gentamicine and aspirin.

ABSTRACT

Electro-chemical oxidation as a method to destroy drug residues like aspirin, tetracycline or gentamicine in water was investigated with C-anodes (modified by manganese oxides) and Pt anodes. The mechanism of aspirin and tetracycline oxidation and the influence of the biocide effect was observed using GC-MS and three different microbiological tests. In general, the biological availability increases with progressive oxidation of the antibiotics.
