摘要：

Adsorption of alpha-tocopherol from ethanol solution on clinoptilolite tuff activated with 4.0 M HCl is studied. alpha-Tocopherol adsorption isotherm is analyzed using the Langmuir, Freundlich, and Redlich-Peterson adsorption theories. The adsorption of alpha-tocopherol from dilute solutions on this sorbent is ascertained to be described by the Langmuir model.
