Sažetak
Titanium as pure metal or commercial titanium alloys have been widely used in dentistry. To know the composition of incorporated reconstructions, there is a need for non-destructive sampling and identification of unknown or suspect elements. In this study the analytical procedure of detection of titanium is reported. The method involves anodic sampling separation and identification of titanium by means of thin layer chromatography (TLC) on precoated cellulose layers. Two thin plates and one cast of elementary titanium and one dental alloy with titanium were analyzed. Chromatograms of samples were developed with a mixture of iso-amyl alcohol, acetonitrile and hydrochloric acid. Excellent detection and identification of titanium as pink colored spot was achieved after spraying with saturated ethanolic solution of alizarin and exposed to NH3 vapor.
