Structural-surface and sorption properties of composite Zr-Ti-SiO2 sorbents based on mineral raw materials of the Kola peninsula for the extraction of non-ferrous metals and radionuclides from aqueous solutions
Samples of composite zirconium-titanium-silica sorbents were synthesized and studied by chemical, X-ray phase, BET and BJH analyses. It is shown that all the obtained samples of silica-containing Zr-Ti-SiO2 sorbents are mesoporous. In this case, the pores have a predominantly wedge-shaped shape with open ends. It was found that the modification of the obtained samples into the H+ form has less effect on their sorption capacity than their conversion to the Na+ form, does not depend on the content of SiO2 in them in the range of 10–30 % and decreases in the range of Cu2+-Cs+-Co2+-Sr2+.
