Abstract

Ion-exchange chromatography is known as one of the most important techniques of stable isotope separation such as nitrogen isotopes. This study aims to investigate the effect of initial feed concentration and migration distance on the efficiency of nitrogen isotope separation. A set of 10 columns filled with the ion-exchange resin Dowex- 50 W X8 with 1 cm I.D. and 100 cm height was set up in order to study the isotope accumulation of 15N by ion-exchange chromatography. The analytical determination of the samples was made by emission spectrometry. The height equivalent to a theoretical plate (HETP) was found to decrease with increasing the migration distance. Results showed that a maximum separation factor of 6.616% could be obtained at an initial ammonium concentration of 0.5 mol/l, feed flow rate of 1.5 ml/min, and migration distance of 70 m. And also the separation factor decreases slightly with the ammonia concentration.
