Adsorption of acetone from aqueous solution on activated carbon can be represented by the Langmuir equation:
\[
\frac{q}{C} = \frac{1}{0.146} + \frac{0.190}{C}
\]
where \( q \) is the adsorbate loading mol/kg, and \( C \) is solute concentration in aqueous solution mol/m³. The maximum adsorbate loading in kg acetone/kg carbon is
