This article is dedicated to the development of a method for the manufacture of granulated carbon sorbents made of powdered rice husk (RH) and lignosulphonate (LS) aimed at absorption of organic and inorganic vapors. The microstructure analysis of the samples reveals that the activation promotes the formation of a higher amount of small pores and the development of a spongy texture of the sorbents leading to carbon content increase when compared to that of the initial sample. The final samples have apparent mesoporosity confirmed by the form of the isotherms referring to the low-temperature adsorption of nitrogen and the results of pore size distribution using the DFT method.
