摘要：This article presents two aspects environnementals: valorization of oil shale ash (OSA) of oil industry onthe one hand, and on the other hand to study the effectiveness of cation adsorption of dye such as the Methylene blue(BM) on material (OSA).In this context, we carried out a parametric study of adsorption, in particular, the time ofcontact, the pH, the amount of the adsorbent, the temperature and the stirring velocity. A study of the kinetics ofadsorption was carried out by two models: pseudo-first order and pseudo-second order, and a modeling by theisotherms of adsorption while basing itself on the models of Langmuir and Frendlich. The maximum capacity ofadsorption of BM on OSA is of 2,464 mg/g, for a concentration of BM of 5 mg/L, an amount of adsorbent of 2 g/L.Material OSA was characterized by several methods such as diffraction of x-ray (DRX), electronic scan microscopy(MEB), electronic microscopy in transmission (MET), x-ray fluorescence (FX), and the infra-red Spectroscopy withtransforms of Fourier (FTIR). In addition, the economic aspect of the use of OSA makes important the re-use of thesematerials considering their capacity to regenerate itself.
