Sk. Bekova et al., A MILD PROCEDURE FOR CONCENTRATING DISSOLVED SUBSTANCES FROM NATURAL AND DRAINAGE WATERS AND THEIR ANALYSIS BY EPR, ATOMIC-ABSORPTION SPECTROSCOPY, AND MASS-SPECTROSCOPY, Eurasian soil science, 24(9), 1992, pp. 104-112
The comparative effectiveness of electron EPR, atomic absorption spect
rometry and mass spectrometry in determining the concentrations of dis
solved substances in unconcentrated and lyophilized samples of water f
rom the Moscow region is investigated. Concentration by lyophilization
is highly effective, making it possible to determine Fe3+, Mn2+, radi
cals of humic origin, and the elements Si, Na, Mg, Al, As, K, Ca, Ti,
Ni, Cu, Zn, Mn, Fe, Pb, and Co in the dry state.
