Sodium dodecyl sulfate adsorption on activated carbon was studied. Adsorption isotherms fit a double Langmuir model, with energy distributions linked to pore size, not surface chemistry.

Area of Science:

  • Surface Chemistry
  • Adsorption Science
  • Physical Chemistry

Background:

  • Sodium dodecyl sulfate (SDS) is a common surfactant.
  • Activated carbon is widely used for adsorption processes.
  • Understanding SDS adsorption is crucial for water treatment and industrial applications.

Purpose of the Study:

  • To investigate the adsorption of sodium dodecyl sulfate (SDS) onto activated carbon in low concentration ranges.
  • To analyze adsorption isotherms and enthalpies.
  • To evaluate adsorbate-adsorbent interaction free energy.

Main Methods:

  • Adsorption isotherm studies using activated carbon and SDS solutions.
  • Calorimetry of adsorption enthalpies.
  • Application of the double Langmuir equation.

  • Interfacial free energy evaluation using the van Oss model.

    • Main Results:

    • Adsorption isotherms were well-fitted by a double Langmuir equation.
    • Calorimetry revealed a wide distribution of adsorption energies.
    • Energy distribution correlated with pore size, not surface chemical properties.
    • Calculated free energy agreed well with the double Langmuir model results.

    Conclusions:

    • The double Langmuir model effectively describes SDS adsorption on activated carbon.
    • Pore structure significantly influences adsorption energy distribution.
    • The van Oss model provides a reliable method for estimating adsorbate-adsorbent interactions.
