Abstract

Today, the separation of various pollutants including heavy metals from industrial wastes is very important. One of the separation methods is adsorption that has attracted great attention in recent years. In this research, cadmium separation from aqueous solution using adsorption onto activated carbon was investigated and mass transfer performed is modeled using a mathematic model. Activated carbon was produced by the chemical activation of grape stalks waste. Identification methods including BET, FT-IR, and SEM were applied to characterize the produced carbon. The effects of process parameters including solution pH, contact time, initial concentration of cadmium, and temperature were evaluated. Results indicated that the adsorption process  is a monolayer process and the adsorption capacity of prepared activated carbon was 142 mg/L. In order to determine the mass transfer parameters, a mat hematical model was presented and the mass transfer coefficients to transfer cadmium ions from the bulk solution to adsorbing onto activated carbon surface were calculated by solving this model. The sensitivity analysis showed that the external mass transfer diffusion and pore diffusion are more important steps. Also, the regeneration and reusability of adsorbent were investigated.
