Description
Summary:The process of adsorption of nickel ions by natural oil shales from deposits in the Tangier region in northern Morocco has been studied experimentally. Thermal degradation and specific surface area of OST 100 were studied by thermogravimetric and BET analysis, respectively, as well as characterization of OST 100 by FTIR, and DRX showed that the shales consisted of SiO2 which is very interesting for adsorption. The results of the adsorption study obtained show Ni2+ was adsorbed by 20 mg/g from wastewater and the elimination process is highly dependent on Physico-chemical parameters (pH, contact time, initial concentration of the adsorbate, and the mass of the adsorbent). The mechanism of nickel ion adsorption was best described by the pseudo-second-order kinetic model and obeyed linear models of the Langmuir isotherms, showing adsorption is done in the area of OST 100, OST 500, and OST 950.
