Modeling of boldine alkaloid adsorption onto MCM-48 mesoporous silica

MCM-48 mesoporous silica was used as adsorbent for boldine alkaloid in MeCN soln. Nonlinear fitting anal. was used to estimate the parameters of the Freundlich, Langmuir and Redlich-Peterson isotherm. MCM-48 silica was characterized by max. adsorption capacity of 405,2 mg/g (Langmuir model, ARE error function). Freundlich isotherm was the best fitted adsorption model.
