摘要：
Sibunite, a carbon sorbent, has been modified with organosilicon monomers containing aminoguanidine, thiocarbamide, malonodiamide, and ammonium dithiocarbamate moieties. The high adsorption activity of the synthesized materials in hydrochloric acid solutions with respect to platinum(IV) ions results from the formation of ion-coordinated platinum(IV) complexes with the chemically active moieties of modifying compounds.
