Abstract
The paper presents data on the possibility of ETAAS analysis, and a technique of this analysis, of salt rocks, their insoluble residues, and organic fractions from these rocks for Au, Pt, and Pd (concentrations from 10–7 to 10–2 ppm). Various techniques for the decomposition of the samples are discussed, and the paper presents information on the extent of Au, Pt, and Pd adsorption from chloride complexes when the POLYORGS-IV complex-forming adsorption agent is applied. The determined atomization parameters of the elements in a graphite furnace are reported. Precious metals are proved to be concentrated in the insoluble residues of the salt rocks and in the slimes (salt wastes) when the salt rocks are processed. The forms in which precious metals are contained in the salt-bearing rocks are determined.
