Sorption Behaviour of I to V Group Elements on a Nickel Hexacyanoferrate(II) Composite Ion Exchanger

Abstract

The sorption of Fr, Ra, Pb, Bi, Eu, Zr, Hf, Th, Nb, Pa and U in trace quantities on a composite ion exchanger with nickel hexacyanoferrate(II) from hydrochloric acid media is described. Particularly radiochemical problems for the isolation of transactinide elements are discussed.

Adsorption Characterization of Strontium on PAN/Zeolite Composite Adsorbent

“…The composite ion exchangers have been used in several studies to treatment of low and medium level liquid radioactive wastes [5][6][7][8][9][10][11][12], to investigate of sorption behavior of I to V group elements (Fr, Ra, Pb, Bi, Eu, Zr, Hf, Th, Nb, Pa, U) [13], to purification of 223 Fr from its decay products [14], to removal of some basic dyes [15], and Na from irradiated samples [16] and to mineralization of biological materials in neutron activation analysis [17].…”

Study of the behaviour of thorium adsorption on PAN/zeolite composite adsorbent

“…The composite ion exchangers have been used in several studies to treatment of low and medium level liquid radioactive wastes [5][6][7][8][9][10][11][12], to investigate of sorption behavior of I-V group elements (Fr, Ra, Pb, Bi, Eu, Zr, Hf, Th, Nb, Pa and U) [13], to purificate of 223 Fr from its decay products [14], to removal of some basic dyes [15], and Na from irradiated samples [16] and to mineralizate of biological materials in neutron activation analysis [17]. This paper deals with the investigation of the best separation and recovery conditions of thorium on a PAN/zeolite composite adsorbent as a function of the initial thorium concentration, pH, shaking time and temperature.…”
