ATOMIC-ABSORPTION AND ATOMIC FLUORESCENCE ELECTROTHERMAL DETERMINATION OF ELEMENTS IN SMALL MARINE SAMPLES

A new version of determination of Ag, Bi, Cd, Pb, Tl in microprober of sea and river water suspension and other objects was developed. The m aterial powder is subject to direct atomization by thermal electric me thods. The microprobe dose is placed on a graphite sounding probe in t he graphite atomizer. The heating of the probe is controlled in depend ently of the crucible, It is shown that the limits for determination o f elements are reduced due to optimization of the processes.
