Research Abstract	Human and veterinary pharmaceuticals are sold, and finally discharged into water environment. The presence of these substances in water environment may pose chronic long-term risks. To reduce pharmaceuticals'load into water environment, it seemed to be effective to treat them in urine using electrolytic process at low voltage. This study focused on the treatability of the electrolytic process. Pharmaceuticals investigated can be oxidized at around 1.0 V, but this process is inhibited by purines. However, the inhibitory effect can be reduced by adding feces, and aeration.
