Calculated isotherm constants are shown in Table 3.The correlation coefficients related to the Langmuir isotherms were much closer to 1 in comparison to the other applied adsorption isotherms for the corresponding temperatures This suggests that the adsorption of mercury was predominately a monolayer process without mutual interactions between the adsorbed molecules.Other adsorption processes describedbytheFreundlich,Temkin,andDubinin–Radushkevich isotherms are less likely to occur.A dimensionless separation factor(RL)defines the favourability of an adsorption process and is described by Eq.(20).
