Evaluation of Intrinsic Reaction Parameters

Once the adsorption equilibrium is reached, the operation conditions are satisfactory for the lamp to be turned on. The model pollutant concentration changes ai c

Compounds 2-chlorophenol and 2,4-dichlorophenol offer special challenges for de-temiining ( i . One can consider that experiments developed for these species fall within the linear section of the adsorption isothenn ( = , Af C ). Using this condition, the k. adiq. m and K q m, groups can be calculated tlirough equations (7-9), (7-10) and (7-11), as reported in Table 7.3. Therefore k j can be calculated while circumventing the need for a prior definition of qi m-
