Abstract

The effects of cross linking with porous cation exchange resin were studied for nitrogen isotope separation. The displacement chromatography was conducted by the resin with cross linking rang from 20% to 40%. A sharp adsorbed ammonium band was maintained for each operation. Enriched 15N isotopes with 0.93% were obtained by 20% cross linking resin and two meters chromatographic operation which started from the natural abundance of ammonium molecule. The effect of cross linking percentage on the height equivalent to a theoretical plate (HETP) was evaluated in the present work and the HETP value is proportional to the cross linking percentage. HETP value of 0.036 cm was obtained at the present system by using 20% cross linking resin.
