in alkaline solution.Different amounts of dextrin were selected to functionalize the MNPs .The samples were characterized by several techniques: XRD, FTIR,\u00a0 AFM, and SEM.The study of the adsorption of the methylene blue dye on the coated magnetite with weight ratio of dextrin(1-2),(1-4),(1-8) as to determine the effectiveness of these surfaces and the possibility of using them as adsorbents in order to treat such contamination. UV-vis spectroscopy was used to determination of adsorption capacities. Isotherms of adsorption were studied at different conditions of temperature, pH, weight of adsorbent and weight of dextrin in adsorbents. This study exhibited the following results:The shapes of isotherms , shows that the methyl green dye on all surfaces follows the Langmayer and freundlish equations in all conditions, and the curved type (S) according to Giles classification. This type of isotherms is achieved in the case of heterogeneous surfaces. factors coated magnetite with weight ratio of dextrin(1-8) as surface showed higher ability from other surfaces\u00a0 for methyl green adsorption. This arrangement did not change in efficacy as the conditions of the adsorption process changed. Depending \u00a0on the increase in the amount of the adsorb ate with increasing concentration or temperature. The study of the adsorption process at different temperatures (318,308,283) K, the results showed that the amount of adsorption of methyl green dye on the above increased by increasing the temperature ( the processes are endothermic ).By adsorption isotherms, the change in the basic thermodynamic values of the adsorption process, such as the Enthalpy (\u2206H), was positive, indicating that the adsorption process is endothermic, while the (\u2206G) is negative, indicating the spontaneous adsorption process\u00a0 and the Entropy (\u2206S) was positive, indicating the irregularity of adsorption processes on all surfaces under study.
