中文摘要:

      研究了处理粘土沉积物时不同浓度盐酸和用量对溶出硼量及硼同位素组成的影响。结果表明,粘土沉积物中硼的溶出量随盐酸浓度的增加而增加,当盐酸浓度相同时,溶出的硼量随所加盐酸用量的增加而增加,加热有利于硼的溶出。实验结果还表明,粘土沉积物硼的溶出量对测定的硼同位素组成没有明显的影响。

英文摘要:

      In this paper ,the influence of concentration and volume of hydrochloric acid on extracted boron con- tent and the boron isotopic composition in clay sediment were studied. The results show that the boron extrac- ted from clay sediments increases with the increase of the hydrochloric acid concentration. When the hydro- chloric acid concentration are the same,the extracted boron increases with increasing amount of hydrochloric acid. Meanwhile,heating is beneficial to boron extraction. The measured δ11B in clay sediments are not obvi- ously relative to extracted boron content from clay sediments.
