Electrostatic Precipitation Atomic Absorption Spectrometry
Volume 44, Number 9 (Nov. 1990) Page 1562-1565
The theory and principles, design, construction, and preliminary evaluation of a system based on the electrostatic precipitation of metals in aerosols on a tungsten collecting electrode, followed by injection of this rod into an electrothermal atomizer for atomic absorption spectrometric determination of the metal, is described. With the use of a manganese aerosol generated by an electrothermal vaporizer, the highest atomic absorption signals—and therefore the optimum charging and collecting efficiency for the geometry of the system as described—were achieved with a negative corona of 15 kV and low aerosol velocity. The system determined copper in the laboratory atmosphere on a near-real-time basis.
