Abstract

Abstract

Chromatographic characteristics for both boron isotopes,using D301-G resin as the stationary phase and water as the mobile phase,were investigated by moment analysis in the given conditions,and the kinetic parameters of boric acid on the stationary phase were evaluated by moment analysis based on equilibrium-diffuse and linear driving force models.The results show that the retention time of ¹⁰B isotope was lager than ¹¹B,and both the axial dispersion coefficient and the overall mass transfer coefficient of boric acid on the D301-G resin phase increase with increasing temperature.The axial dispersion coefficient was evaluated to be 1.08 cm²/min and the overall mass transfer coefficient was 0.65 min-1 at room temperature..
