Significance and Use | ||||||||||||||||||||||||||
Ultrasonic extraction using dilute nitric acid is a simpler and easier method for extracting lead from environmental samples than are traditional digestion methods that employ hot plate or microwave digestion with concentrated acids (1), (3), (5), (6). Hence, ultrasonic extraction may be used in lieu of the more rigorous strong acid/high temperature digestion methods (for example, see Ref (1) and Test Method E1613), provided that the performance is demonstrated using accepted criteria as delineated in Guide E1775. In contrast with hot plate or microwave digestion techniques, ultrasonic extraction is field-portable, which allows for on-site sample analysis. |

1. Scope | ||||||||||||||||||||||||||
1.1 This practice covers an ultrasonic extraction procedure for the extraction of lead from environmental samples of interest in lead abatement and renovation (or related) work, for analytical purposes. 1.2 Environmental matrices of concern include dry paint films, settled dusts, soils, and air particulates. 1.3 Samples subjected to ultrasonic extraction are prepared for subsequent determination of lead by laboratory analytical methods. 1.4 This practice includes, where applicable, descriptions of procedures for sample homogenization and weighing prior to ultrasonic extraction. 1.5 The values stated in SI units are to be regarded as the standard. 1.6 This practice does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this practice to establish appropriate safety and health practices and determine the applicability of regulatory limitation prior to use. |
