I. INTRODUCTION In studying the surface chemistry of activated carbon, a number of research methods using various assay techniques have been used. It is necessary to compare the various data obtained from the determination of the surface chemical properties. In this paper, five different methods were used to determine the chemical properties of activated carbon obtained from the modification of raw material carbon. The following technologies are used: Elemental analysis, acid-base reaction, acid titration, thermal decomposition, infrared spectroscopy, calorimetry for water and benzene wetting. Water vapor adsorption and Volta potentiometry.
