Abstract
The adsorption of pyridine onto crosslinked starch microspheres (CSMs) was investigated by experimental and theoretical methods. The adsorption capacity of CSMs towards pyridine increases with the increasing of pyridine concentration, and by lowering the temperature, adsorption would be accelerated. The adsorption behaviour of CSMs to pyridine is in agreement with the Langmuir isothermal equation. The research results show that the adsorption process is exothermic, and the adsorption force mainly derives from enthalpy changes. The thermodynamic parameters of adsorption process show that the adsorption behaviour of CSMs towards pyridine is of a physical type. 17 Refs.
