海水中的钕(Nd)同位素性质稳定,被广泛用于海洋学过程的研究。由于海水中Nd含量很低,且在测定过程中易受钐(Sm)的影响,因此富集和纯化成为海水中Nd同位素分析的必要步骤。传统的分离方法通常是利用氢氧化铁共沉淀法富集海水中的稀土元素(REEs),再用LN-C50-A树脂对Nd进行分离纯化。但富集过程较为耗时。本研究采用NOBIAS螯合树脂对海水中的稀土元素进行富集,优化了上样pH值、NOBIAS PA1螯合树脂淋洗酸浓度、LN-C50-A树脂淋洗酸体积等实验条件。结果表明,当pH=4.7时,NOBIAS PA1螯合树脂对钕的回收效率大于99%;LN-C50-A树脂对钕分离纯化的回收效率大于93%。本方法重现性好(RSD < 1.5%,n=3),且系统误差对钕同位素的测定无显著影响(RSD < 5%,n=5),能满足海水中钕及其同位素分析精度的要求。
