Abstract
A method to analyse iron-59 in water is introduced. The procedure of this method includes concentration by co-precipitation with hydroxides purification by anion exchange, electrodeposition in NH{sub 4}H{sub 2}PO{sub 4}-(NH{sub 4}){sub 2}CO{sub 3} system and final measurements of beta activity with a background beta-counter. The effect of iron carrier amount and pH value of water sample on the carrying Fe-59, and the effect of concentration hydrochloric acid, flowrate of adsorption and elutriation with 6 mol/L HCl-1% H{sub 2}O{sub 2} solution on the adsorption efficiency have been studied. The experimental results indicate that for 101 water sample, both the chemical and radiochemical yields are greater than 90%. For {sup 51}Cr, {sup 60}Co, {sup 65}Zn, {sup 95}Zr-{sup 95}Nb and {sup 137}Cs the decontamination factor is greater than 10{sup 3}. The minimum detectable limit of this method is 3.8 x 10{sup -3} Bq/L.
