3.2.5. Adsorption isotherms
Fig. 7 shows experimental equilibrium adsorption isotherm for
nitrite ions onto ZnCl2/450-AC.
Langmuir and Freundlich isotherm models were both employed
using Equations (4) and (5), respectively. Linear plots were
observed in each case, and the values of the adsorption plot parameters
are summarized in Table 7.
