| Abstract |
Two extraction and two quantitation procedures are given for the quantative determination of lead in paints along with recommended QA/QC practices. The procedures were evaluated with 0.10 g samples of synthetic or old real-world paints that had been crushed or pulverized. Both extraction procedures gave recoveries greater than 90%. The hotplate boiling HNO3/H2O2 procedure combined with atomic absorption spectrometry (AAS) analysis yielded precisions of 4 to 8% RSD for samples greater than 1000 ppm Pb, with a linear sample analysis range of 1000 to 20,000 ppm Pb. Inductively coupled argon plasma (ICP) analysis gave precisions of 6 to 10% RSD for samples above 300 ppm Pb and a linear analysis range of 100 to 200,000 ppm Pb. Using the microwave HNO3/HCL extraction procedure, AAS had precisions of 2 to 4% RSD for samples above 1000 ppm Pb and an analysis range of 200 to 4,000 ppm Pb, and ICP had precisions of 2 to 6% RSD for samples above 300 ppm Pb with an analysis range of 20 to 40,000 ppm Pb. |
