The aim of the work is to develop and optimize methods for the synthesis of the above (thia)calix[4]arenes, suitable for the extraction of strontium radionuclides, actinides and lanthanides from radioactive waste and natural objects, creating the solid extractants based on them. The study of the sorption properties of the obtained new materials. A number of derivatives of (thia)calixarenes were synthesized, their structure was established by NMR and IR spectroscopy. A number of sorption materials for the extraction of radioactive isotopes of lanthanides and actinides from aqueous solutions, which can be used in analytical chemistry and the processing of high-level waste from spent nuclear fuel, has been obtained.
