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
