ESM 222 Fate and Transport of Pollutants in the Environment Lab #2: Physicochemical Properties Report due 04/21/08 Objective: Understand the behavior of different types of organic compounds as governed by their: ± Volatility ± Solubility ± Density with respect to water You will also be trained to use the GC/MS for analysis of your samples. Methods: There will be two groups working each time block, with two different fume hoods. We will use the following organic compounds: ± Trichloroethylene, TCE ± Toluene ± Acetone ± MTBE ± Dodecane ± A mixture of these five compounds at 20% by volume Review ahead of time the Material Safety Data Sheets (MSDS) and obtain from the literature the values of the properties you are going to observe, so that you have an idea of what to expect. These compounds have been chosen given the relatively wide range of properties. We have added a red dye (Sudan IV) so that you can more clearly see the NAPL layer; note that this changes the properties slightly compared to literature values. Before starting, make a list of the number of vials you are going to need for analysis and label them clearly. I recommend S1-TCE for solubility of TCE by Group 1, V3-Mix for the volatilization of the mixture by Group 3 and so on. Keep a running log of your activities in a notebook so you can later use it to complete your report.
