Sorption of Phenobarbital and Amobarbital on Na-montmorillonite

Abstract:

In order to characterize the sorption kinetics of phenobarbital sodium and amobarbital sodium on natural Na - montmorillonite, the influence of the initial drug concentration and clay particles sizes was investigated. Equilibrium isotherms have been measured and analyzed using a Langmuir isotherm model. The affinity of drugs sorbed onto clay varied in the following descending order: phenobarbital sodium ] amobarbital sodium, respectively 11.2 and 9.1 mg/g. Also, sorption of phenobarbital sodium and amobarbital sodium on Na-montmorillonite was studied as a function of pH. The results show that adsorption of the drugs is highest below the pHZPC due the neutrality of the drugs which adsorbs via an attraction of the positively charged surface sites at lower pH by weak van der Waals forces.
