It contains integrated assessment in how much hydrolyzed wood lignin and analcyme-containing rock are able to immobilize uranium, radium and thorium compounds from aqueous solutions and contaminated podzolic soil. So the experiments under laboratory and field conditions were made. Influence of liquid phase pH and salinity on sorption efficiency was studied. For identification of sorption mechanisms we used sequential extraction and IR approaches. The experiments results shown, that hydrolyzed lignin effectively and strongly sorbs radioelements not only from aqueous solutions, but from the podzolic soil too. Immobilization of uranium, radium and thorium proceeded efficient due to special properties of its functional groups, irregular structure and ability to entrap low-weight organic substances and generation of complex physical-chemical interre¬lations different by action mechanisms, with sorbates. There was established, that uranium and radium are sorbed by analcyme rock from aqueous solutions. Ion exchange with surface Si-OH, Al-ОH, Mn-OH groups is the possible mechanism of uranium sorption by rock. The radium sorption may be due to ion exchange in groups mentioned above and absorption in interior cavities of alumocilicate framework. The sorption of radionuclides by analcime rock from contaminated podzolic soil was found to be of low effective.
