Supporting of some ferrocyanides on polyacrylonitrile (PAN) binding polymer and their application for cesium treatment

Transition metal ferrocyanides were supported on polyacrylonitrile (PAN) as a binding polymer and were used for removal of radiocesium. The sorption capacity was determined to be 1.22 and 0.55 mol g −1 for KZnHCF-PAN and KCuHCF-PAN, respectively. Different parameters affecting the sorption process w...

Zusammenfassung:Transition metal ferrocyanides were supported on polyacrylonitrile (PAN) as a binding polymer and were used for removal of radiocesium. The sorption capacity was determined to be 1.22 and 0.55 mol g −1 for KZnHCF-PAN and KCuHCF-PAN, respectively. Different parameters affecting the sorption process were studied as chemical nature of the aqueous solution and flow rate of feed solution. The regeneration of the used sorbent was studied and also using the regenerated sorbents in other sorption cycles was studied up to four cycles.
