1. Detecting Aluminum in Drinking Water Erica Sandoval

2. Why Is There Aluminum in Drinking Water Treatment −Microorganisms −Organic Matter

3. Aluminum’s Toxicity Alzheimer's Nervous system Respiratory problems Skeletal problems Toxic to fish Forest decline

4. Hypothesis & Goal Low levels of Aluminum in drinking water can be detected using a Photometric Technique and GC-MS. 1.Research previous work 2. Use fluorescence technique 3. Use GC-MS 4. Apply to different sources

5. Fluorescence

6. Fluorimetric Determination of Aluminum Form complexEliminate Interferences Create micellar system Measure Fluorescence

7. Gas Chromatography-mass Spectroscopy Form complex GC used for separation MS used for identification of components

8. Thanks Welch Foundation for providing me with the opportunity to work on this project Dr. Altmiller for guidance and support
