Drainage of untreated wastewater from the textile industry due to the use of toxic compounds in it causes pollution in aquatic environments and major environmental and health problems. Therefore, the aim of the present study is to compare the performance of activated carbon coated with AC-ZnO composite as an adsorbent to remove the AB-113 from the aqueous solution. The present study is an experimental-laboratory study in which the effect of independent parameters has been investigated. FTIR and XRD analyzes were performed to determine the composition of the composite. Isothermal and kinetic adsorption at different concentrations were evaluated to evaluate the process. The results of physical-chemical analysis confirmed the correctness of the composite structure. Optimal conditions for AB-113 (with a concentration of 100 mg/L, a composite dose of 0.5 g/L, a reaction time of 15 minutes and pH = 3) 98.2% were obtained. The results of the study of isothermal and kinetic adsorption for dye showed that the adsorption process follows the isotherm of Freundlich (R2 = 0.9859) and Pseudo-second-order. The maximum adsorption capacity of AC-ZnO composite was determined using Langmuir model 333.33 mg/g. Thermodynamic parameters showed the non-spontaneity and endothermic in nature of adsorption process. The present study showed that nanoparticle stabilization technology can be used on activated carbon as an effective and efficient adsorbent to remove dye from aqueous solutions.
