The methods for the boron separation and its isotopic determination in [WT5BX]foraminifera was developed, using Amberlite IRA 743 resin and the mixture of cation-exchange resin (H + form) and anion -exchange resin (ion exchanger II, HCO - 3 form).

• 本文初步建立了一种用硼特效树脂和阴、阳混和离子交换树脂相结合进行有孔虫中硼的分离和同位素测定的方法。
