Technique for separating boron isotope with boron specific resin ion-exchange chromatography

The invention provides a process for separating boron isotope with a boron special-effect resin ion exchange chromatography. The process adopts chelate-typed ion exchanging resin-boron special-effect resin, separates B from boric acid solution, and uses hydrochloric acid or nitric acid as eluent to separate the boron isotope in the boric acid solution by the adsorption of the boric acid on resin columns and the washing of the eluent on the boric acid adsorbed on the resin. According to the process of the invention, the enrichment ratio of the B can be enriched from natural 20 percent or so to 91 percent or so, with fast enrichment speed. The process of the invention is a simple and high-efficiency process which separates the boron isotope from the boric acid solution.
