STUDY OF ADSORPTION OF DRUG AND CALCULATION OF FREUNDLICH ADSORPTION ISOTHERM

Abstract

Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. Adsorption is a surface-based process while absorption involves the whole volume of the material. The term sorption encompasses both processes, while desorption is the reverse of it. Adsorption is a surface phenomenon. The aim of present study was to study the effect of adsorbent (charcoal) on the adsorption of oxalic acid. It can be concluded that Cs increases exponentially with increases in Y and log K value was 0.148 and 1/n was equal to 0.674.

Keywords: Solubility, oxalic acid, Charcoal, Adsorption
