چکیده
In this work, an eco-friendly, stable, simple, new super adsorbent adsorption properties based on biopolymer sodium alginate was successfully deliberate by a combination of a simple crosslinking method. Preparation two hydrogel   (SA-g-P(Ac-co-AM) hydrogel and  the second hydrogel after loading CNT/ZnO onto   hydrogel  and these new hydrogel surfaces were prepared from two monomers (acryl acid, acrylamide) to remove  Chloramphenicol CHZ drug .The physical characterizations of new super adsorbent hydrogel nanocomposite were performed using XRD, FTIR, TGA, EDX  and  TEM. The practical experiments involved calculation of the best wavelength and study of best condition of adsorption factors like: effect of equilibrium time, weight of hydrogel nanocomposite, temperature solution, pH solution and adsorbent regeneration experiments (desorption). The removal percentage of CHZ drug   increase from 55.45  to 89.8%, and adsorption capacity decrease from 65.5 to 110 mg g-1 on to hydrogel nanocomposite. The isotherm Freundlich and isotherm Langmuir were too introduced that all data follow the model Freundlich isotherm in the presence of CHZ drug. The change enthalpy (∆H) is value positive indicating the adsorption method endo-thermic presses and spontaneous of change Gibes free energy (∆G) negative value, and positive value of   change entropy (∆S).
