Abstract
  In this study, the adsorption and thermodynamic parameters of Diazepam drugs adsorbed onto six activated carbons were determined. A simulated gastric fluid was applied at pH 1.2 for 4 h. The samples were characterized by FTIR, N2 isotherm at 77 K, and CO2 at 273 K. The experimental adsorption was fitted ...  Read More
