عنوان انگلیسی Elaboration and Characterization of Organo-Ghassoul (Moroccan Clay) as an Adsorbent Using Cationic Surfactant for Anionic Dye Adsorption
چکیده انگلیسی مقاله This study used the cation exchange approach to carry out significant chemical modifications in Moroccan Rhassoul clay by inserting a cationic surfactant (N-Methyl-N,N,N-trioctylammonium chloride) through the void between the leaves. In order to investigate the chemical composition and surface characteristics of clay as it was being treated, Fourier transform infrared spectroscopy (FTIR), X-ray fluorescence (XRF), X-ray diffraction (XRD), and thermogravimetric analysis (TGA) were explored as physical approaches.. The treatment of a textile effluent (blue reagent 19 RB19) using this modified clay as an adsorbent has demonstrated a substantial removal efficiency of the pollutant load.The experiments were carried out under static conditions to optimize certain parameters such as the pH value, the adsorbent concentration, as well as the characteristic time of contact. The maximum adsorption capacity was 80% with a mass-volume ratio of 0.6 g / l at pH = 5. The kinetic study has revealed that the second-order model is better suited for a contact time of about 60 min. The study of adsorption isotherms shows that the Langmuir model correctly describes the adsorption process with an extreme adsorbed amount up to 204 mg/g at 25 ° C.
