Abstract |
Water samples taken in a building corrosion control study having high lead levels often contained particulate material at the bottom of the acid-preserved sample bottles. Scanning electron microscope analysis of the particles revealed the presence of tin and absence of lead, indicating the source of lead to be lead-tin solder. A leaching study was performed to further investigate the effectiveness of the historically-standard 0.15% HNO3 preservation procedure in dissolving lead corrosion by-products. Results indicated that the standard preservation technique of acidification to 0.15% HNO3 was sufficient for dissolving lead from lead-tin solder particles, but not dissolving tin. |
