A vaccine is being purified from 20 L of cell culture supernatant by adsorption. The adsorption process follows Langmuir isotherm KL = 0.5 g/L and CBmax = 1.5 g/g. Theconcentration of the vaccine in the cell culture supernatant is 0.01 g/L. How much adsorbent(in g) will be required to adsorb 95 % of the vaccine?
