This study  includes the synthesis and characterized of new adsorbent of Porcelanite- Melamine- Formaldehyde Polymer (PMFP). The chemical structural formula of this adsorbent was confirmed by FTIR, XRD and SEM techniques. The adsorption ability of PMFP toward Azure dyes A, B and C  has been  studied using UV-Visible spectrophotometry. This technique has been utilized to construct the relation between the amount of adsorbate Azure dyes and the equilibrium concentration (isotherms). Factors affecting adsorption, such as contact time, pH, temperature and adsorbent dose, were evaluated. The equilibrium of adsorption was modeled by using the Langmuir and Freundlich isotherms models. The thermodynamic functions ?H, ?G and ?S were calculated and were explain in the mean of the chemical structure of the adsorbate.

Keywords: PMF Polymer, Organic Azure A, B and C dyes, Langmuir and Freundlich  isotherms
