A New Method for Standardless Analysis in ETA-AAS Applied to the Determination of Lead Associated with Air Aerosol

Future of atomic spectrometry for environmental analysis

“…to attempt a future perspective of this discipline. Of the several Sample preparation techniques range from little or none, for approaches that can be used to project the future, 9 74 He plasmas, may find more extensive application. Speciation measurements will become more prevalent and readily As noted earlier, however, environmental analytical laboratories are often constrained to utilize compliance methodologimplemented as a consequence of the multidimensionality afforded from tandem and combined sources, on-line chemical ies (such as those of the US EPA, Occupational Safety and Health Administration, various national Department of the manifolds and increased availability of reference materials certified for species content.78 Sample consumption and minimEnvironment organizations) as analytical protocols are largely driven by regulation and require use of specific procedures ization of waste will be addressed through FI and on-line sample preparation techniques, direct analysis of solids, approved by the relevant regulatory agency.…”

Atomic Absorption, Atomic Emission, and Flame Emission Spectrometry

“…It was argued that, assuming 100% atomization efficiency, the absorbance at the plateau is proportional to the total number of atoms injected into the furnace. This permitted development of a method of standardless analysis (158) based on this plateau absorbance value and an experimentally derived spectroscopic constant. This was applied to the determination of Pb and Cd in fruit juice (159), and several metals in air particulates (104,158,160).…”

An EP-SAW for measurements of particulate matter in ambient air

“…Electrostatic precipitation of particles has been routinely used in applications, such as the collection of airborne microorganisms [1], sampling of cloud and fog droplets [2] and the determination of lead in atmospheric aerosols [3]. Electrostatic precipitators operate on the principle of the attraction of charged particles to an oppositely charged collector.…”
