Question

2. An expended activated carbon column has adsorbed 0.3 g Aldrin (a pesticide) per
gram of GAC. Desorption into water percolating through the activated carbon column
follows the Freundlich isotherm with Kf = 1.0 (m3/g)1/n and n = 2. Determine if the
percolating water is likely to become saturated with Aldrin. The solubility of Aldrin in
water is 0.2 g/m3.
