Thermodynamics of Phenol Adsorption on the Microsphere Based on Starch

Abstract:

In order to purify the wastewater polluted by phenol, the research of the thermodynamics of phenol adsorption on the adsorbent was very important. In this paper, a type of crosslinking starch microsphere (SM) has been synthesized by reversed phrase suspension method with soluble starch as raw material and N, N’-methylenebisacrylamide as crosslinking agent. And then the adsorption thermodynamics of SM toward phenol had been studied, and the adsorption capacity increased with the increasing of concentration of phenol solution, lower temperature ccould accelerate adsorption. The research results showed that the adsorption process was exothermic, could proceed spontaneously, and the adsorption driving force came from the enthalpy change mainly. The thermodynamic parameters of adsorption process showed that the adsorption behavior of SM towards phenol belongs to physical adsorption.
