4. A solution containing naphthalene (two benzene rings together) and guanine is known to exhibit competitive inhibition in adsorption. The Langmuir isotherm constants, for the two solutes individually and for the carbon of interest are: Naphthalene: a =0.4366 mg/mg b= 0.3297 L/mg Guanine: a=0.3723 mg/mg b= 0.3585 L/mg Mixed carbon adsorption: The initial solute concentrations, CoA and CoB are both 10 mg/l (naphthalene and guanine in a mixed solution). If the final concentration of naphthalene is 1 mg/l, what is the final concentration of guanine? How much carbon (mg/l) is required to accomplish these concentration reductions? Separate carbon adsorption: If the amount of carbon found above was added to each of two flasks and a 10mg/L solution of naphthalene was added to one of the flasks and a 10mg/L solution of guanine was added to the other flask, what would be the equilibrium concentrations in both flasks?
