Anion metathesis of the Cu-EDA SAMMS™ using sodium ferrocyanide makes a mixed metal complex lining the pore walls of the nanoporous sorbent, making a highly efficient Cs exchanger.
Cesium-SAMMS™
Radiocesium is one of the primary concerns involved in the management of nuclear waste. Effective separation of cesium from complex mixtures, especially in the presence of large quantities of sodium or potassium, can be quite challenging. Ferrocyanide SAMMS™ has been shown to be highly effective for selectively removing cesium, even in the presence of large excesses of sodium or potassium, and even at low pH.
