  1. Jenna Simandl, Civil Engineering, University of Alabama CuongDiep, Chemical Engineering, University of Cincinnati Sidney Stacy, Biomedical Engineering, University of Cincinnati Formaldehyde detection and removal in direct alcohol fuel cell effluent NSF Grant ID No:DUE-0756921

  2. Introduction • Spectroscopy and Perfluorosulfonicacid (PSA) membrane • Acetone • Formaldehyde • Water Interference http://www.chem.agilent.com/en-US/products-services/instruments-systems/molecular-spectroscopy/8453-uv-vis-diode-array-system/Pages/photodiode_array_benefits.aspx

  3. Goal • Collect sufficient amount of data to be able to test the hypothesis that membrane additives can minimize water interference in optical sensing of acetone and formaldehyde

  4. Tasks • Task 1: Training • Task 2: Acetone exposure calibrations • Task 3: Repeat for formaldehyde • Task 4: Draw conclusions • Task 5: Deliverables

  5. Timeline

  6. Training Received • Literature Review • Membrane preparation • UV/Vis Spectroscopy demo • Acetone exposure testing practice Worrall, A. D., Bernstein, J. A., Angelopoulos, A. P. (2013). “Portable method of measuring gaseous acetone concentrations,” Talanta, Vol. 112, No. 1, pp. 26-30.
