Development and practical evaluation of the scheme for 137Cs concentrating from seawater using chitosan and mixed ferrocyanides of Zn-K and Ni-K

A two-stage method for 137 Cs concentrating from seawater has been developed and adopted using composite ferrocyanide sorbents CFS Ni-K and CFS Zn-K(F). The suggested approach showed high efficiency that gives the opportunity to assess 137 Cs content in the seawater without using low-background dete...

Description
Summary:A two-stage method for 137 Cs concentrating from seawater has been developed and adopted using composite ferrocyanide sorbents CFS Ni-K and CFS Zn-K(F). The suggested approach showed high efficiency that gives the opportunity to assess 137 Cs content in the seawater without using low-background detectors. The data on 137 Cs content has been obtained for the Japan, Okhotsk, and Bering seas using the suggested strategy.
