Synthesis and Characterization of Some Chemically Modified Clays and Their Usage as Adsorbents for Various Undesired problems in Petroleum Oil fields

Abstract

synthesis and characteristics of some chemically modified clays and their usage as adsorbents for various undesired problems in petroleum oil field. In the present study, the pure raw Bentonite clay has been modified by Inorganic way (acid treatment) and by organo-modified ways like ( DMSO) or (EDTA).Structural characteristics of the various samples were investigated through XRD, ICP, FTIR, S.A, SEM, TEM, AFM and Zeta potential. Textural and morphological characteristics were estimated from low temperature adsorption-desorption isotherms of N2 , pore size distribution analysis. Adsorption activities of the prepared organo-functionalized Bentonite samples were examined by the uptake behavior of Fe3+ ion as a typical example for severe polluted heavy metals in industrial waste water especially in petroleum field. The adsorptive results were correlated with various characteristics to determine the most prominent species in heavy metal ion adsorption processes. Metal ion uptake studies via adsorption isotherm and kinetics were also investigated.
