QUESTION
An aqueous solution containing 0.012 mol phenol/L is to be treated at 20 °C with activated carbon to reduce the concentration of phenol to 0.00006 mol/L. Laboratory experiments with adsorbent particles 1.2 mm in diameter in a well-agitated vessel have confirmed that the rate of adsorption is controlled by external
- The adsorption equilibrium isotherm for aqueous phenol solution and activated carbon can be determined from the following data:
q, kmol/kg 0.0022 0.0033 0.0036 0.0038 0.0040
c, kmol/m3 0.0010 0.0050 0.0080 0.0100 0.0120
Fit the data to the Linear, Freundlich and the Langmuir Isotherms. Which provides a better fit to the data? Write the complete form of the isotherm.
