Study of Adsorption Capacity of Dibenzotiofen Molecules on Mesoporous Carbon with Pore Geometry Model

Maria Ulfa, Farhah Nayla Fawzia

Abstract

Adsorption models in a simple and accurate way to describe the geometry of the pores have been studied and validated experimentally to predict the adsorption capacity dibenzotiofen molecules on mesoporous carbon. The model is designed according to the size of the pore channels of mesoporous carbon and molecular arrangement dibenzotiofen that goes into the pores. To test the accuracy of the model is done by comparation with results of analysis of nitrogen adsorption-desorption to calculate the volume filled. The results showed that the results of the experimental adsorption data are within the range of values of the pore volume of mesoporous carbon. These results indicate that the pore geometry model molecule can accurately predict the adsorption capacity of a molecule in a mesoporous material.
