Abstract

This study aims to remove of Disperse red (DR) from aqueous solution using nanocellulose surface and astragulas plant surface and to compare the efficiency of the two surfaces in terms of absorption and application of agents. Affects adsorption such as the temperature effect, PH effect, the amount of the adsorption surface and the contact time for the efficiency of adsorption as well as knowledge of adsorption isotherms such as Frendelch and Langmuir and knowledge of thermodynamic processes to find out the free energy, enthalpy and entropy (random). Where the results of adsorption of DR dye by the surface of nanocellulose were as follows, the equilibrium time is 10 minutes, the optimum surface quantity is 0.005 grams, it works under all thermal conditions and has an acidity effect 3>7>11, which is more suitable for Freundlich's isotherm. The results of adsorption of DR dye on the NC surface were spontaneous through the negative value of Gibbs free energy (∆G0), and endothermic (chemical adsorption) through the positive value of enthalpy ((∆H0) as for the adsorption of DR dye on the surface of the astragulas plant as follows, the equilibrium time is 90 minutes, the optimum surface amount is 0.02g, it works under all thermal conditions and has an acidity effect 3>7>11,
