摘要	When clay sediments were dissolved by hydrochloric acid, there will form large amounts of water insoluble hydroxide precipitation of Al, Fe and rare earth elements which can absorb boron strongly in high pH solutions. The hydroxide precipitation will greatly affect the extraction of boron and the determination of boron isotope. In this experiment, a new three-step ion-exchange method for the separation and purification of boron was proposed. Firstly, all the Al, Fe and rare earth elements which can generate water insoluble hydroxide, were removed by cation resin column with AG 50 W x 8. Next, boron in the sample solutions without Al, Fe and rare earth elements was extracted by boron special resin column with Amberlite IRA 743. Finally, the boron solutions were further purified by anion and cation resin mixed with Ion-exchanger If and AG 50 W x 8. The experimental results showed that the recovery of boron was more than 90% and no obvious boron isotope fractionation could be achieved using this three-step ion-exchange method. Therefore, this method could meet the needs of the high-precision determination of boron isotope of clay sediments.
