In order to meet the accuracy and timeliness requirements of natural uranium trade reinspection, the working conditions for determining uranium in imported uranium trioxide by wavelength scattering X-ray fluorescence spectroscopy were optimized. Suitable digestion methods, digestion vessels, digestion time and temperature, mylar film, sample quality for determination, and other sample pre-treatment conditions were selected for optimization. The measuring conditions of X-ray tube voltage and current, spectroscopic crystal, wave crest and background angle(2θ), measure the time were determined. The precision, accuracy and reliability of the method were evaluated. The results show that the linear correlation coefficient of the working curve of the method is 0.999 6, and the relative standard deviation (RSD) is 0.029%~0.056%. The relative error between the measurement results and the recommended value of the reference material is ≤0.027%. Compared with the titration method, the absolute deviation of the method is 0.003%~0.093%, the results are accurate and reliable, and The efficiency is 5 times that of titration. The method can meet the requirements for rapid batch analysis of imported uranium trioxide samples.

为满足天然铀贸易复检对准确性和时效性的要求,对采用波长散射X射线荧光光谱法测定进口八氧化三铀中的铀工作条件进行了优化研究,对消解方式、消解器皿、消解时间和温度、麦拉膜、测定用样品质量等样品前处理条件进行了优化选择,确定了X光管电压电流、分光晶体、波峰和背景角度(2θ)、测定时间等仪器测定条件,并对方法的精密度、准确度、可靠性等进行了评估。结果表明:该法工作曲线的线性相关系数为0.999 6,相对标准偏差(RSD)在0.029%~0.056%之间;测定结果与标准物质推荐值之间相对偏差≤0.027%;与滴定法相比,该法绝对偏差在0.003%~0.093%之间,结果准确可靠,工作效率是滴定法的5倍。该法可满足进口八氧化三铀样品快速批量分析的要求。

In order to meet the accuracy and timeliness requirements of natural uranium trade reinspection, the working conditions for determining uranium in imported uranium trioxide by wavelength scattering X-ray fluorescence spectroscopy were optimized. Suitable digestion methods, digestion vessels, digestion time and temperature, mylar film, sample quality for determination, and other sample pre-treatment conditions were selected for optimization. The measuring conditions of X-ray tube voltage and current, spectroscopic crystal, wave crest and background angle(2θ), measure the time were determined. The precision, accuracy and reliability of the method were evaluated. The results show that the linear correlation coefficient of the working curve of the method is 0.999 6, and the relative standard deviation (RSD) is 0.029%~0.056%. The relative error between the measurement results and the recommended value of the reference material is ≤0.027%. Compared with the titration method, the absolute deviation of the method is 0.003%~0.093%, the results are accurate and reliable, and The efficiency is 5 times that of titration. The method can meet the requirements for rapid batch analysis of imported uranium trioxide samples.

目前,进口八氧化三铀贸易结算以《铀矿石浓缩物的标准规格》(ASTM C967—2020)[1]中规定的检测项目和含量限值签订贸易合同,检测项目包括铀含量和水分等26个参数。双方以铀金属量进行结算,约定金属铀量的差异0.2%以内(含)以中方复验数据为准,0.2%~0.3%(含)取平均数,0.3%以上可启动第三方仲裁机制;标准样品的测定值与标准值差限值为0.1%。铀含量检测结果作为贸易结算的主要依据,其准确性和时效性至关重要。
铀含量测定的方法有氧化还原滴定法[2-3]、库伦滴定法[4-5]、戴维斯-格雷滴定法[6-7]、同位素稀释质谱法等[8]。这些方法准确度较高,但存在化学前处理操作流程较长、程序繁琐、人为因素影响大等缺点,很难满足八氧化三铀样品快速批量分析的要求。
近年来,X射线荧光光谱法在核工业分析测试领域发展迅速,该法因具有分析速度快、易于操作、可同时测定多种元素等优点,已逐渐成为一种重要的分析手段[9-14]。在借鉴国外《X射线荧光光谱法测定铀产品的方法》(ASTM C1254)[15]基础上,率先在国内开展了锶内标法在溶液法制样、X射线荧光光谱法测定天然铀产品中铀的可行性研究[16-17],并建立了企业标准[18-19]。试验对用波长色散X射线荧光法测定天然铀产品中的铀的条件进行优化研究,以期为建立行业标准提供依据。

2 试验结果与讨论
收起
2.1 样品前处理条件的选择
2.1.1 消解方式
样品消解完全是保证数据准确测定的前提,选择合理的消解试剂和消解方式至关重要。选取3种不同消解方式对八氧化三铀样品进行消解试验,结果见表2。
由表2看出:硝酸体系针对难溶样品不能完全溶解,溶液中出现红棕色沉淀物,结合文献[8]推断,此沉淀物为硝酸不溶铀,致使测定结果显著偏低;硝酸-氢氟酸体系虽能溶解,但加热时间过长,且因需要冒干氢氟酸,使玻璃器皿腐蚀,增加消解难度;硝酸-磷酸消解彻底,同时磷酸可以增加溶液黏度,消解样品时不易产生溅射,使样品消解较完全,溶液清亮,表明硝酸-磷酸体系可作为消解试剂的最佳选择。
2.1.2 消解器皿
分析高含量铀时选择消解器皿主要考虑加热消解过程中溶液不易溅射损失、不发生转移损失。实验室常见承载样品的器皿有烧杯、锥形瓶、坩埚等。经典的滴定法,如EJ277—1986[2]、GB/T 11848.1—2008[3]中均采用烧杯溶样,试验稍做改进,采用瓶身更高的带刻度锥形瓶溶样。由于采用内标法[16-17],可抵消定容体积不一致因素带来的误差,同时为尽量减少溶液的转移损失和减少操作人员对铀的接触和泄漏风险,不采用容量瓶转移定容,直接利用溶样过程中带刻度的锥形瓶稀释。消解和溶液转移过程中溶液损失的误差,可达1%以上。对于天然铀贸易中规定差异小于0.2%的要求,溶液损失1滴(0.05 mL)都会成为误差的主要来源,因此样品消解过程中完整保留溶液至关重要。试验中,称样、溶样、定容以同一锥形瓶为载体,简化了操作流程,操作人员可控性强,适合批量化检测。
2.1.3 消解时间和温度
消解温度主要考虑溶样过程中反应不能过于剧烈,防止剧烈沸腾和爆沸,宜用较低温度溶样,本方法选择250 ℃低温溶样。试验中发现,采用磷酸-硝酸体系在温度为250 ℃时,约15 min可将样品消解至溶液清亮。考虑到适当延长消解时间溶解更彻底,试验确定消解时间为20 min,同时确定硝酸提取时间为10 min。
2.1.4 麦拉膜
麦拉膜是一种高分子聚酯薄膜,可用于承载样品。薄的麦拉膜透光性好,X射线通过穿过麦拉膜探测样品信号,因此一般应尽可能地选择薄的麦拉膜。但麦拉膜对酸的耐腐蚀性不强,而本方法属于酸溶液法,因此,选取2种不同规格的实验室麦拉膜进行腐蚀性试验,结果见表3。
由表3看出:3.6 μm的麦拉膜耐腐蚀性较差,易发生溶液穿透。由于溶液中U和Sr浓度足够高,综合考虑仪器光管安全性,试验选用厚度6 μm的麦拉膜。但在实际样品杯制作过程中,存在麦拉膜人为破裂的情况,因此在测定样品前,需将样品杯溶液静置1~2 min,观察是否漏液,如漏液须重新制作样品杯,以保证仪器安全。
2.1.5 测定用样品质量
因X射线在液体中容易穿透,试验中应尽可能保证试样达到无限厚度,以避免不饱和厚度下溶液体积差异带来的误差。选取一种标准物质,按照样品前处理方法制备溶液1份,在电子秤上用一次性塑料吸管分别吸取溶液样品10、15、20 g,在确定的仪器工作条件下测定U强度(I(U))和Sr强度(I(Sr)),测定结果见表4。
由表4看出:样品质量由10 g增至15 g时,U和Sr强度升高;样品质量≥15 g时,U和Sr测定强度反而降低,说明样品质量为15 g时,U和Sr的特征射线强度已无法穿透溶液,溶液达到饱和厚度。考虑到样品杯容量较大,同时为了覆盖天然铀样品中铀含量在不同范围下的饱和厚度,选择测定用样品质量为20 g。
2.2 仪器测定条件的确定
2.2.1 分光晶体
分光晶体是X射线光谱仪的重要色散元件,作用是根据布拉格衍射定律,将样品发射的特征X谱线按波长顺序分开。色散率是重要指标之一,其晶面间距2d越小,色散率越高,谱线分开程度也越好。试验选用仪器配备的晶体、2d及适用范围见表5。
由表5看出:LiF220和LiF200晶体适用于U的Lα1谱线和Sr的Kα1谱线,LiF220晶体的2d值小于LiF200晶体,LiF220色散率较好,但LiF200反射强度占优。考虑到U-Lα1和Sr-Kα1为相邻谱线,溶液中U、Sr含量足够高,为减少U、Sr相互谱线干扰,提高分辨能力,选择LiF220作为分光晶体。
2.2.2 X光管电压电流
一般地,对于测定元素工作电压为临界激发电压的2~4倍[20]。U的特征谱线Lα1波长为0.091 1 nm,临界激发电压为21.764 kV,工作电压范围为43.528~87.056 kV;Sr的特征谱线Kα1波长为0.087 5 nm,临界激发电压为16.101 kV,工作电压范围为32.202~64.404 kV。试验考察了XRF光管在不同工作电压和电流条件下,铀的荧光强度变化情况,结果如图1所示。
由图1看出:在XRF光管工作电压相同条件下,随电流增大,荧光强度增大;在XRF光管工作电流相同条件下,随电压增加,荧光强度也增大。为减少荧光计数率的误差,提高分析精度,应尽量提高U和Sr的荧光强度。实验室AxiosMAX型波长色散X射线荧光光谱仪的最大激发电压为60 kV,最大功率为4.0 kW,结合U和Sr的激发电压范围,并参考相关XRF测定铀文献[11-13],确定U和Sr工作电压均为60 kV,工作电流均为60 mA。
2.2.3 波峰和背景角度(2θ)
依据相关参考文献[21],LiF220晶体2d=0.285 nm,U和Sr特征谱线在LiF220晶体分光情况下的峰值理论2θ见表6。
由于环境、仪器等存在差别,使得理论角度和实际角度存在一定偏差,依据上述前处理方法,量取含U和Sr溶液进行通道扫描试验,以在波峰最高处为实际峰值角度,确认2θ分别为35.796 4°(Sr-Kα1),36.266 0°(U-Lα1)。
选取背景可改善元素的检出限和准确度[22],一般应选择无谱线干扰、波峰两侧平滑处作为背景;但考虑到U-Lα1和Sr-Kα1为相邻谱线,因此,选择各自不相邻谱峰一边的平滑处为背景,U和Sr共用这2个背景,依据通道扫描试验结果,经仔细辨别谱线干扰,确认背景角度2θ分别为34.793 2°和38.676 4°。
2.2.4 测定时间
测定时间对计数统计误差和检出限有影响[22],适当延长测定时间可提高测定结果精密度。按上述前处理方法制备铀溶液,并分别移取4份20 mL溶液置于4个样品杯中,按照谱峰时间10、30、50、70 s测定铀强度,重复测定6次,测定时间对测定结果精密度的影响结果见表7。
由表7看出:测定时间在≤50 s区间内,随测定时间延长,相对标准偏差(RSD)呈下降趋势,说明测定结果精密度越来越高;但测定时间延长至70 s时,RSD大幅升高,说明此时测定精密度变低,这主要是测定时间较长,使得光管照射发热,溶液底部会逐渐产生气泡所致。综合考虑,确定测定时间为50 s。
2.3 工作曲线
称取标准样品0.93、0.95、0.97、0.99、1.01、1.03 g(精确到0.1 mg),同时称取碳酸锶0.600 g(精确到0.1 mg)。按照1.3.1步骤制成溶液,依次用X射线荧光光谱仪测定铀强度。以铀/锶强度比为横坐标、铀质量为纵坐标,绘制工作曲线,结果如图2所示。可以看出:方法工作曲线方程为y=69.527 0x-4.802 4,经计算得出,线性相关系数R2=0.999 6,说明铀/锶强度比对铀质量呈良好的一次线性关系。
2.4 方法的精密度
选取6个不同批次的进口八氧化三铀样品,每个批次样品分别称取6份,按1.3.1步骤和优化的前处理和仪器测定条件考察方法的精密度,结果见表8。可以看出:铀测定结果的RSD在0.029%~0.056%之间,说明方法的精密度较高。
2.5 方法的准确度
称取4个标准物质(含2个定值样)按未知样品进行测定,本方法准确度试验结果见表9。可以看出:本方法测定结果与标准物质推荐值之间相对偏差≤0.027%,满足贸易质控中规定标准样品的测定值与标准值偏差低于0.1%的要求,说明该方法准确度较高。
2.6 方法的可靠性
为验证方法的可靠性,抽取20个进口八氧化三铀样品,分别采用本方法和电位滴定法[3]进行测定试验,并计算2种方法的绝对偏差,结果见表10。可以看出,2种方法的测定结果基本一致,绝对偏差在0.003%~0.093%之间,表明采用X射线荧光法测定铀的方法准确可靠,满足贸易中不同方法差值应小于0.2%的要求。
2.7 不同测定方法对比分析
根据测定的1 554个样品,分别采用X射线荧光光谱法和电位滴定法进行对比测定试验,结果见表11。可以看出:与电位滴定法相比,X射线荧光光谱法可减少试剂消耗和人为操作误差,提高分析精密度和自动化水平,分析时间可从175 min缩短至35 min,工作效率提高5倍。
