1 Jenna Simandl, Civil Engineering, University of Alabama Cuong Diep, Chemical Engineering, University of Cincinnati Sidney Stacy, Biomedical Engineering, University of Cincinnati NSF Grant ID No:DUE

2 Introduction  Spectroscopy and Perfluorosulfonic acid (PSA) membrane  Acetone  Formaldehyde  Water Interference 2 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 3

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

5 Timeline Task/Week Training Acetone Formaldehyde Conclusions NSF Paper Final Paper Presentation Final Poster 5

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