Losev, Vladimir N.; Parfenova, Victoriya V.; Elsuf’ev, Evgeney V.; Borodina, Elena V.; Metelitsa, Segey I.; Trofimchuk, Anatoliy K. published the artcile< Separation and preconcentration followed by ICP-OES and ICP-MS determination of precious metals using silica gel chemically modified with dithiocarbamate groups>, SDS of cas: 128-09-6, the main research area is metal silica gel dithiocarbamate separation preconcentration ICPOES ICPMS.
Silica gel chem. modified with dithiocarbamate groups (DTCS) was used for separation and preconcentration of precious metals and their subsequent determination in geol. 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-anal. DTCS quant. 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 sep. precious metals from matrix components and to sep. kinetically inert precious metals from kinetically labile ones.
Separation Science and Technology (Philadelphia, PA, United States) published new progress about Adsorbents. 128-09-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C4H4ClNO2, SDS of cas: 128-09-6.
