ABSTRACT
Potassium nickel hexacyanoferrate composite with magnetite finds application in the recovery of cesium from low-level liquid waste using magnetic assistance. The apparent sorption capability of hexacyanoferrate-magnetite composite and potassium nickel(II) hexacyanoferrate(II) matched indicating no loss in sorption capability as a consequence of coating to nanoscale magnetite substrate. Selectivity for cesium in a broad pH range, selectivity in the presence of high concentration of sodium nitrate, and fast exchange kinetics are additional features of the nanocomposites.
