عنوان المقالة:تحضير وتشخيص متراكب الاتابلكايت – اوكسيد الكريفين واستخدامه في دراسةحركية امتزاز صبغة اليزارين من اوساطها المائية Preparation and Characterization of Graphene Oxide – Attapulgitecomposite and its use in kinetic study of Alizarin Dye Adsorptionfrom Aqueous Media
ATTAPULGITE clay was modified in this study by the graphene oxide sheets and the clay was diagnosed before and after modification using several techniques (Fourier-transform infrared spectroscopy FT-IR, X-ray powder diffraction XRD, Scanning electron microscope SEM , energy dispersive spectroscopy EDX ) ,The surface of the attapulgite clay (before (Ata) after modification bygraphene oxide (Ata-GO) ) was applied to adsorption of the Alizarin dye from its water solutions through the application of several kinetic models (pseudo first-order model , pseudo second -order model , intraparticle diffusion model ),It was found that the practical results follow pseudo second -order model. The process of modification on the surface of the mud has improved the adsorption properties where the quantity dye adsorbed is equal to (55,81) mg/g by the surfaces (Ata ,Ata-GO) respectively.
