The sorption capacity of carbon-mineral sorbents for Cu(II) ions, methyl orange, and iodine was studied. The optimal carbonization temperature for 100:5, 100:10, and 100:20 mixtures was 600°C, which agreed with experimental IR spectroscopic, elemental analytical, and modern thermal analytical data for carbonized sapropel—bentonite-clay mixtures. The carbon-mineral sorbent prepared by carbonization of 100:5 sapropel—bentonite-clay mixture showed high maximum adsorption for Cu(II) ions, methyl orange, and iodine. The volumes of meso- and micropores of all studied sorbents were determined using molecular probes. Carbon-mineral sorbents prepared by carbonization of sapropel—bentonite-clay mixtures at 600°C in an oxidizing medium were found to be meso-macroporous.
