چکیده
|
We study the photocatalytic and photoelectrocatalytic degradation of diclofenac sodium which is a widely used non-steroidal drug known for its anti-inflammatory and analgesic properties. for this purpose nanocrystalline titania (nc-tio2) films are employed in the presence of naoh under uva irradiation. in particular upon application of a forward (anodic) bias (+1v) the photodegradation rate is decreased while a reverse (cathodic) bias (-1v) leads to rate increase. furthermore,iv curves are obtained (5mv/sec scans) under black light (uva) illumination at various concentrations of the pharmaceutical in the presence of 0.25m naoh. the results show that currents of up to 8ma can be achieved in the case of 5 × 10-5mol l-1 diclofenac concentrations.
