The possibility of group concentration for subsequent arc atomic emission analysis (AAEA) with a multichannel emission spectra analyzer (MESA) aimed at determining trace amounts of platinum metals (PMs) and gold in secondary and technogenic materials using commercial or newly synthesized (via the thiomethylation reaction) sorbents containing nitrogen and sulfur was studied. The conditions for sorption...
The possibility of group concentration of As, Bi, Sb, Se, and Te using sulfur- and nitrogen-containing sorbents with the subsequent determination by ICP-AES and DCA-AES with MAES in analysis of metal-containing recyclable raw material is studied. Conditions of ICP-AES and DCA-AES with MAES analysis of sorption concentrate from solutions or from solid phase are selected. The developed method makes...
