Selective extraction of naturally occurring radioactive Ra2+

Chem Soc Rev. 2005 Sep;34(9):753-61. doi: 10.1039/b506073g. Epub 2005 Jul 19.

Abstract

Organic extractants play a significant role in the selective removal of radioactive cations from waste streams. Although, literature on the selective removal of man-made radioactive material such as Americium (Am) is widespread, the selective removal of naturally occurring radioactive material such as Ra2+ is only mentioned sporadically. This tutorial review deals with the selective extraction of the highly radiotoxic Ra2+. Special attention is paid to different types of organic extractants used.
