Understanding Chemical Adsorbent Behavior
A component of Performance of Pollutant Adsorbents
To fully understand the behavior of chemical adsorbents and to better inform judgments on their use and appropriateness, it was essential to develop a deep understanding of their chemistry. This included testing and optimizing the analytical and preparative techniques to be used.
Work Completed
- Collecting both conservation and chemical literature on generic and specific adsorbent properties and use
- Conducting carbon, hydrogen, nitrogen, and sulfur analysis
- Conducting BET specific surface measurement
- Performing thermogravimetry, differential thermal analysis, and mass spectrometry to identify adsorbed species
- Conducting microprobe analysis and imaging for surface morphology
- Conducting laboratory preparation of adsorbents with altered physical properties
- This work was carried out on selected adsorbents to address specific issues unique to each. Not all of the work was applied to all adsorbents
