Calixarene Nanoextractants for Radiowaste Partition

Description

We propose a new class of perspective extractants of longlived radionuclides on the base of nano-sized calixarenes functionalized with phosphine oxide groups. In such compounds the binding groups may be best located around a metal cation, increasing the extraction efficiency and selectivity to a great extent.

Innovative Aspect and Main Advantages

The nano-sized calix[4]arene phosphine oxides, developed jointly by the Institute of Organic Chemistry NASU (Kiev) and Khlopin Radium Institute (St. Petersburg) extract simultaneously actinides, lanthanides, technetium and palladium from real HLW hundred times more efficient than the industrial extractants. In three contacts ~ 99,9 % of gross a-activity, more than 98 % of Tc and Pd were recovered from real HLW on the “MAYAK” plant (Chelyabinsk).

Areas of Application

High level wastes partitioning technology. Radiowastes management.




Stage of Development

The Institute of Organic Chemistry of the National Academy of Sciences of Ukraine produces different calixarene extractants. Speciaists of the Khlopin Radium Institute, St.-Petersburg possess experience in development of radiowastes partition technologies.
