Analytical Method of Gamma Emitters in Seawater Using Coprecipitation with Nickel Hexacyanoferrate(II) and Iron(III)Hydroxide

Abstract

The analytical yield of gamma emitters in seawater by coprecipitation method with nickel hexacyanoferrate(II)and iron(III)hydroxide was confirmed using spiked radioisotope(¹³⁷Cs)and stable elements. Ninety-nine% of spiked ¹³⁷Cs was adsorbed on nickel hexacyanoferrate(II), and 88–94% of spiked Ce, Co, Mn, Ru, Zn, Zr was adsorbed on iron(III)hydroxide. This analytical method is considered to be very efficient and practical for environmental radiation monitoring from the view of quick and simple operation, especially easy analysis of plural samples.
