Activated Carbon Adsorption

Considerable data on the adsorption of several pesticides and related nitrophenols on activated carbon have been reported (Weber and Gould 1966). Carbon loadings of 40-53% indicate economic feasibility for removal of trace quantities of these persistent compounds. Rate and Langmuir equilibrium constants for the pesticides are shown in Table 8.2.7. The quantity of pesticide adsorbed per gm of carbon at complete monolayer coverage of the carbon surface (Xm values) indicates high ultimate carbon loadings. B-1 values, which relate to energies of adsorption, indicate that relatively high residual concentrations
