摘要：

In this study, the elimination of phenol compounds from phenolic solutions by adsorption method in column was studied. The adsorbent is a polymer's bead which is synthesized from an apatite by a method based on cross-linking process. Studies showed that the synthesized adsorbent (P-ap) can retain phenol with a high adsorption capacity (about 244 mg/g of apatite) and a slow reaction kinetics (about 4 h), which can be described by an equation corresponding to a pseudo second order. The exploitation of the adsorption isotherm indicates that the best fit is obtained with the Freundlik model. Results of regeneration of phenol show that adsorbed phenol remains almost unstable and can be desorbed using only distilled water.
