Separation and preconcentration followed by ICP-OES and ICP-MS determination of precious metals using silica gel chemically modified with dithiocarbamate groups [Текст] / Vladimir N.

Silica gel chemically modified with dithiocarbamate groups (DTCS) was used for separation and
preconcentration of precious metals and their subsequent determination in geological samples
and their processing products by inductively coupled plasma optical emission spectrometry and
inductively coupled plasma mass spectrometry. DTCS was characterized by TGA/DSC, FT-IR, and
CHNS-analysis. DTCS quantitatively extracted Au3+, Pd2+, Pt2+, Pt4+ at 20°C from 0.5 to 4.0 M HCl
media and Rh3+, Ir4+, Ru4+, and Os4+ at 95°C in the presence of 0.025 M SnCl2. Two-column
procedure was proposed to separate precious metals from matrix components and to separate
kinetically inert precious metals from kinetically labile ones
