Abstract


The effective removal of atmospheric hazardous pollutants using activated carbon for the real-world application is a crucial and reliable process. Therefore, the performance comparison of ground activated carbon BPL 4×6 (ACb212) based on varied outlet pressure of benzene vapour were analyzed in ambient condition (room temperature and pressure). The maximum adsorption capacity was found ~110 mg. g-1) for all pressure regions. However, the competition showed maximum capacity for higher pressure region i.e., 50.5 mg. g-1, minimum capacity at lower pressure region 7.96 mg. g-1, and moderate for moderate outlet pressure 20.6 mg. g-1. On the other hand, the partition coefficient (PC) behaved inversely to the sorption capacity i.e., high PC (397 mol.kg-1. Pa-1) at the low outlet and low PC (1.47 mol.kg-1. Pa-1) at high outlet benzene partial pressure regions. The adsorption capacity on ACb212 followed the classical Langmuir isotherm of Type-1 at low and high-pressure outlet pressure regions, while a retrograde behaviour isotherm (Type-1) was observed for lowest benzene outlet partial pressure region. Furthermore, the linearized Langmuir isotherm analysis also confirmed the existence of two or more sorption sites for gaseous benzene.
