摘要:铀矿浓缩物的溯源研究在核法证学中具有重要地位,通过测量其中的铅、锶同位素丰度比能为溯源提供部分地理指示信息。对铀矿浓缩物中铅、锶同位素的精准测量主要受制于大量铀与微量铅、锶的分离、富集。本文利用Eichrom Sr树脂对铅、锶的特效吸附性,通过正交试验对影响铅、锶回收率的主要因素(淋洗酸度、流速、体积)进行了优化,确定了最佳淋洗条件;进而利用UTEVA树脂对铀的特效吸附性,与Eichrom Sr树脂联用,实现了铀矿浓缩物中大量铀与微量铅、锶的分离,有效降低了因铅、锶洗脱液中铀含量过高而引起的基体效应。实验结果表明:铅、锶回收率均>90%,铅、锶洗脱液中的铀含量低于500ng,优于文献报道值(48.8μg)。利用该方法对实际铀矿浓缩物样品进行测量,分析结果显示铅、锶同位素丰度比可以作为铀矿浓缩物的地理溯源判据,为今后建立铀矿浓缩物中铅、锶同位素数据库提供技术支持。

Application of Eichrom Sr Resin to the Separation and Enrichment of Lead and Strontium in Uranium Ore Concentrates

ABSTRACT

BACKGROUND:

The traceability study of uranium ore concentrates plays an important role in nuclear forensics. By measuring the abundance ratios of lead and stontium isotopes, the results can provide some geographical indication information for traceability.

OBJECTIVES:

To achieve the separation of large amounts of uranium from trace lead and strontium and to establish a set of methods for separating lead and strontium from uranium ore concentrate, while providing technical support for the establishment of a lead and strontium isotopes database in uranium ore concentrate.

METHODS:

Based on Eichrom Sr resin's adsorption properties for lead and strontium, the main factors (acidity, current velocity and volume) affecting the recovery of lead and strontium were optimized by orthogonal testing. The best washing conditions have been determined. The combination of UTEVA resin and Eichrom Sr resin can effectively reduce uranium content in lead and strontium eluent and thus reduce the matrix effect.

RESULTS:

The results show that the recovery of lead and strontium is more than 90% and the uranium content in lead and strontium eluent is less than 500ng, an improvement on the reported value of 48.8μg.

CONCLUSIONS:

The actual uranium ore concentrate samples were measured by this method. The results show that the lead and strontium isotope abundance ratios can be used as the geographical traceability criteria for uranium ore concentrates, providing a technique for the future establishment of lead and strontium isotope databases for uranium ore concentrates.

KEY WORDS: Eichrom Sr resin, uranium ore concentrates, lead, strontium, matrix effect

HIGHLIGHTS

(1) Uranium ore concentrates were selected as the study object, and the separation of lead and strontium from uranium under different conditions has been researched.

(2) The combination of Eichrom Sr resin and UTEVA resin can effectively reduce uranium content in lead and strontium eluent. The uranium content was lower than the reported value of 48.8μg.

(3) A preliminary source investigation based on the abundance of lead and strontium isotopes in the actual uranium ore concentrates has been studied.

(4) The separation method provides technical support for the establishment of the database of lead and strontium isotope abundance ratios in uranium ore concentrates.
