DIRECT DETERMINATION OF IRON DRUG RELEASED FROM TIO2 NANOTUBES VESSEL

Abstract

This study focused on using TiO2 nanotubes as a vessel for drug release. the release of iron ion from titanium dioxide nanotubes was done. TiO2 nanotubes synthesized by anodization. Anodization method was done using 60 volts between two titanium plate as an electrode. the distance between two electrodes 6.5 cm. the electrolyte, contained (0.5w/w NH4F, 2w/w H2O, 97.5 w/w ethylene glycol) the anodization process accomplished at room temperature. Scanning electron microscopy (SEM) was used for examine the morphology of the surface on synthesized TiO2 nanotubes. SEM images show that the prepared tubes were within the nanoscale TiO2 nanotubes mouth at 80 nm in diameter. Synthesized TiO2 nanotubes used as vessel for iron drug release. The determination of iron which release from the tubes measured using spectrophotometric method. The percentage of drug release reached % 99.6.
