The proposed method for treating water and liquid radioactive waste from transuranic elements and uranium by using 5,11,17,23-tetrakis(dipropylphosphoinilmethyl)-25,26,27,28-tetrapropoxycalix[4]aren is distinctive by performing, for the purpose to enhance the treatment quality, operations for binding radionuclides into chemical compounds be treating the radioactive waste in the low-acid environment, with the uranium concentration of 3 ... 65 mg/dm3, ratio of more than10:1 between the content of calixarene and the content of uranium in water, and the holding time of the obtained mix of 1 ... 3 hours, and providing the ultrafiltration of the obtained product by polymeric or inorganic membrane filter.
