%X The results of XPS measurements of commercially pure titanium <i>cp</i>-Ti) before and after chemical treatment are presented. We have measured XPS spectra of core levels (Ti 2<i>p</i>, O 1<i>s</i>, C 1<i>s</i>, F 1<i>s</i>) and valence bands of coarse-grained <i>cp</i>-Ti before and after standard acid treatment accepted in dentistry (in 1% HF and 40% HF for 1 min). It is found, that acid treatment of <i>cp</i>-Ti reduces the content of hydrocarbons increasing the surface energy and bio-compatibility of Ti-implants. On the other hand, it is fixed that oxygen concentration on the surface of the acid treated <i>cp</i>-Ti is much higher than for the untreated sample, because the acid treatment removes the contaminated surface layers, increases their reactivity, provides a better passivation and formation of thick protecting TiO<sub>2</sub> layer.
