| چکیده | ||
| The present study used a free radical copolymerization approach to synthesize hydrogel of new poly sodium alginate (acrylic acid-co-acrylamide) grafted ZnO/CNT hydrogel nanocomposite. SA-g-P(Ac-co-AM)/ZnO-CNT hydrogel nanocomposite was characterized via X-ray diffraction (XRD), Thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), and Field emission scanning electron microscope (FE-SEM). In the adsorption experiments, Clonazepam (CLZ) drug was used. In this study absorption process was carried out in shaker water batch for the drug and an equilibrium system to investigate the adsorption of drug onto SA-g-P(Ac-co-AM)/ZnO-CNT hydrogel nanocomposite. The parameter influenced the adsorption capacities, like equilibrium time, initial of drug concentrations, pH solution temperature of solution and adsorbent dosage. The maximum adsorption capacities and removal percentage of CLZ were 95.14 mg g-1 (85.56%). The adsorption thermodynamics for drug were in accordance with isotherm Freundlich model. It is shown that adsorption of the drug is spontaneous and endothermic presses. | ||
