1 CHEMISRTY 423 Flame Atomic Absorption Spectroscopy Laboratory Project Spring 2008 The atomic spectroscopy mini-project is an open-ended guided-inquiry laboratory exercise. Your approach should be to read through the reference material (cited below and attached), develop a plan-of-action to meet the stated objectives in the most efficient manner possible, perform the experiments, take notes and ask questions. Your group will develop and optimize a method for the preconcentration and quantitation of heavy metals in water samples using a membrane disk and flame atomic absorption spectroscopy. Materials: 1. Choose three metals, from the following list, as the subjects for this set of experiments: Cd 2+ , Co 2+ , Cu 2+ , Ni 2+ , Pb 2+ , Zn 2+ . 2. Complexing ligand: sodium diethyldithiocarbamate (Na-DDTC). 3. Membrane disk: Supelco 47-mm ENVI-DISK, catalog number 57171. 4. Vacuum pump and supporting chemicals and glassware. 5. Varian SpectrAA 220FS instrument.
