Extraction properties of organic salts of acidic phosphoryl podands and trioctylamine with respect to cesium

The extraction ability of the organic salt of acidic phosphoryl podand (1,5-bis(o-(hydroxyethoxyphosphoryl)phenoxy)-3-oxapentane) and trioctylamine with respect to cesium in nitric acid and carbonate media is investigated. The extraction ability of the organic salts of acidic phosphoryl podand and trioctylamine are compared to those of dibenzo-18-crown-6 and di-tert-butyldicyclohexano-18-crown-6. It is shown that organic salts of this type have a significant advantage in the extraction of cesium from nitric acid and carbonate solutions.
