DETERMINATION OF IRON, ALUMINUM AND VANAD IUM IN TITANIUM-ALLOYS USEDIN PROSTHESIS FOR BONE IMPLANTS BY INDUCTIVELY-COUPLED PLASMA-ATOMIC EMISSION-SPECTROMETRY (ICP-AES)

Inductively Coupled Plasma Atomic Emission Spectrometry shows advantag e relative to other methods because of the easeness in eliminating int erferences,speed of analysis and excellent agreement among the results . An application of ICP-AES technique is described in this work for th e determination of iron, aluminium and vanadium in titanium alloys use d in prosthesis for bone implants. The analytical conditions were dete rmined through the use of a multielementar standards solution and afte r that the sample solutions, digested with 50% (v/v) hydrochloric acid , were analysed.
