| Abstract: | Summary 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. |
