Adsorption of volatile sulphur compounds onto modified activated carbons: Effect of oxygen functional groups

- HNO3 oxidation incorporates a higher amount of functionalities than O3 oxidation.
- The loss of porosity is compensated by the massive incorporation of oxygen groups.
- HNO3 oxidation increases OH groups in AC and the ETM and DMS adsorption capacities.
- The oxygen functional groups in the AC surface did not affect the DMDS adsorption.
- COSMO-RS predicts the important role of OH groups for VSC adsorption.
