Detecting Aluminum in Drinking Water
Erica Sandoval
Why Is There Aluminum in Drinking Water
• Treatment−Microorganisms−Organic Matter
Aluminum’s Toxicity
• Alzheimer's• Nervous system• Respiratory problems• Skeletal problems • Toxic to fish• Forest decline
Hypothesis & Goal
• Low levels of Aluminum in drinking water can be detected using a Photometric Technique and GC-MS.
1. Research previous work2. Use fluorescence technique
3. Use GC-MS4. Apply to different sources

Fluorimetric Determination of Aluminum
• Form complex•Eliminate Interferences•Create micellar system•Measure Fluorescence
Gas Chromatography-mass Spectroscopy
• Form complex
•GC used for separation
•MS used for identification of components
