| Resumen |
The lead compounds triethyllead (Et3Pb+), diethyllead (Et2Pb2+) and inorganic lead (Pb2+) were successively extracted from urine. The sample solutions were prepared using 0.5M DL-malic acid as a buffer for Et3Pb+, 0.75M H2O2-0.004M HClO4 for Et2Pb2+ and 1.6M DL-malic acid-0.05M K2Cr2O7 for Pb2+. Sodium borohydride was added and the Pb hydrides formed were determined by atomic absorption spectrophotometry. The recovery rates were 99.7, 97.3, 91.4, and 95.9% for Et3Pb+, Et2Pb2+, Pb2+, and total Pb respectively. The coefficients of variation for the same 3 ions and total Pb were, respectively, 5.6, 7.5, 2.1, and 2.9% and the detection limits were 0.005µgPb for Et3Pb+ and Et2Pb2+ and 0.1mggPb for Pb2+. |
