摘要：The study of the adsorption of ions H2PO4-by polypyrrole (PPY) and polyaniline (PANI) requires the preliminary synthesis of the two adsorbents by reaction of oxidation on the monomers. The examination of the adsorption is carried out by taking account of various parameters (masse of the support/volume of the solution of ions H2PO4- ratio, time of contact, pH of the medium, temperature). Ions H2PO4-are adsorbed according to the model of Langmuir for the PPY; the increase in the active sites plays a very significant role on the level of the retention. And it is adsorbed according to the model of Freundlich for the PANI. Moreover, the pH and the temperature do not seem to have of notorious effect on adsorption of ions H2PO4-for the two adsorbents
