Objective To establish a method for rapid determination of chromium content in aluminum food packaging based on fiber laser induced breakdown spectroscopy. Methods The sensitivity and limit of detection of laser induced breakdown spectroscopy and flame atomic absorption spectrometry optimized by laser pulse width, energy and baseline were evaluated with reference materials, and the 2 kinds of techniques were applied to the detection of aluminum food packaging samples, and the corresponding results were compared. Results For fiber laser induced breakdown spectroscopy, the time consumption was 2 min, the limit of detection was 5.2 μg/g, and the detected Cr content of coca cola packaging, aluminum foil paper and aluminum box were 45, 22, 21 μg/g, respectively. For flame atomic absorption spectrometry, the time consumption was 4 h, limit of detection was 7.2 μg/g, and the detected Cr content of these 3 samples were 136, 16, 14 μg/g, respectively. Conclusion This method is superior to the conventional flame atomic absorption spectrometry method in terms of analyzing speed, limit of detection and cost, and its detection results of commercial samples are similar to those of flame atomic absorption spectrometry, which proves the reliability of this method and its potential applicability in analysis tasks of limited time and large sample quantity.

目的 建立基于光纤激光诱导击穿光谱技术快速检测铝质食品包装中铬含量的检测方法。方法 使用标准物质分别评估经激光脉宽、能量和扣基线优化后的激光诱导击穿光谱法及火焰原子吸收光谱法的灵敏度和检出限, 并将两种技术应用于市售铝制食品包装样品的检测中, 将相应结果进行对比。结果 激光诱导击穿光谱法耗时2 min, 检出限5.7 μg/g, 可口可乐、铝箔纸和铝盒中铬含量的检出结果为45、22、21 μg/g; 原子吸收分光光度法耗时4 h, 检出限7.2 μg/g, 3种样本的检测结果分别为136、16、14 μg/g。结论 本方法在分析速度、检出限、成本上均优于传统火焰原子吸收光谱法, 且实际样本检测结果与火焰原子吸收光谱法接近, 证明了本方法的可靠性, 有望应用于短时间内大量样本的检测任务。

铝制食品包装具有耐压、耐高温、耐湿度变化、质轻、光泽度高、延展性好、装饰性好、可回收性等优良特性而受到广大消费者的欢迎[1]。但若长期食用铝制包装食品, 会导致铬等重金属在体内聚集而造成慢性中毒。GB 2762—2022《食品安全国家标准 食品中污染物限量》中规定大部分食品中铬的含量不得超过1.0 mg/kg, GB/T 3190—2020《变形铝及铝合金化学成分》中规定食品行业用铝及铝合金材料中的铅、汞、镉、铬总含量不得超过0.01%。因此, 有必要开发铝制食品包装中铬含量的检测方法。
目前常用的检测方法是用强酸消解铝质金属样品, 并用原子吸收分光光度法(atomic absorption spectrometry, AAS)、电感耦合等离子体-发射光谱法(inductively coupled plasma-optical emission spectrometry, ICP-OES)或电感耦合等离子体-质谱法(inductively coupled plasma-mass spectrometry, ICP-MS)进行检测[2]。这些方法虽然具有稳定性好、适用范围广等优点, 但其需要消耗大量强酸, 且与金属反应剧烈, 具有一定的危险性和污染性, 而且实验步骤烦琐且耗时, 需要耗费较多人力, 实验通量较低, 很难及时完成需要检测大量样本的任务。另外, AAS、ICP-OES和ICP-MS等仪器较为昂贵, 使得样品检测成本较高。因此开发快速、环保、经济的检测方法尤为重要。
激光诱导击穿光谱法(laser induced breakdown spectroscopy, LIBS)具有仪器结构简单、无需样品前处理、分析速度快、可原位分析等优点而被运用在材料科学[3-4]、法证鉴定[5-6]、地质学[7-8]、农业[9]、考古学[10]、生命科学[11]等广大领域中。特别值得注意的是, 近10年来光纤激光器得到了长足的发展, 其具有价格低、光束质量高、可靠性高、操作及维护简单等优点, 受到了越来越多分析化学家的关注。经过研究者们验证, 使用了光纤激光器的激光诱导击穿光谱法(fiber laser-laser induced breakdown spectrometry, FL-LIBS)在信噪比、校准曲线线性度和检出限(limit of detection, LOD)等分析效能参数上与普遍使用的灯泵浦固体激光器类似[12-15], 甚至能够获得更为简单谱图[16]。有学者研究了进一步提高其检测灵敏度、LOD和分析准确度的方法, 如开发双激光架构[17-20]、额外引入电火花激发源[21-25]、开发扣背景算法等[26-28]。但目前较少基于FL-LIBS开发食品包装中重金属的快速检测方法的报道。本研究拟基于本实验室前期创制的FL-LIBS分析平台, 开发铝制食品包装中铬的检测方法, 将结果与其他LIBS研究相对比, 并将本方法应用于实际铝制食品包装的检测中, 并将结果与火焰AAS检测结果进行对比验证, 为铝制食品包装分析提供准确、快速、绿色、经济的检测方案。

1.3 实验方法
1.3.1 FL-LIBS仪器的架构及实验方法
(1)仪器架构
FL-LIBS分析平台架构如图1所示。激光脉冲经由反射镜反射后, 再经过聚焦透镜聚焦至样品表面产生等离子体, 其发射的光由一个芯径为600 μm的光纤线进行收集并传输至微型光纤光谱仪中(采集范围: 396.5~484.7 nm, 仪器半峰宽: 0.11 nm)。光纤激光器、微型光谱仪和二维移动平台的协同控制由自制电子控制卡进行控制。
(2) FL-LIBS实验方法
将样品放在二维移动平台上, 并调节聚焦透镜位置使得激光聚焦于样品表面。激光波长1064 nm, 发射频率为2 Hz。设置二维移动平台以0.2 mm/s的速度进行连续移动, 光谱仪的积分时间为3 s, 每张光谱图是6次激光单脉冲作用的累加结果, 每个铝标准品及样品重复采集30张光谱数据。
1.3.2 原子吸收分光光度法
本研究中使用的原子吸收分光光度法在姚波[29]的实验方案上进行了少量改动, 具体如下。
(1)样品的制备
将100 mL分析纯浓盐酸缓慢加入200 mL去离子水中, 配制成盐酸水溶液(1:2, V:V)。准确称取铝制食品包装0.2 g (精确到0.0001 g), 缓慢加入共20 mL上述盐酸水溶液, 停止剧烈反应后滴加2 mL过氧化氢溶液, 加热使试样完全溶解, 并进一步加热煮沸10分钟去除过量过氧化氢, 冷却。将溶液移入50 mL容量瓶中, 定量加入5 mL氯化锶溶液(100 g/L)后定容。
(2)铬标准系列溶液的配制
取6只10 mL的容量瓶, 分别加入1000 μg/mL的标准溶液0、10、20、40、80、100 μL, 用铝基底溶液定容至10 mL, 配制成1、2、4、8、10 μg/mL质量浓度的标准系列溶液。
(3)火焰原子吸收分光光度仪检测条件
使用空气-乙炔富燃火焰, 空气流量15.0 L/min, 乙炔流量2.8 L/min, 波长357.9 nm, 灯电流10 mA, 狭缝宽0.7 nm。将配制好的铬标准系列溶液以及样品溶液按照上述仪器条件进样分析, 读取各个样品的吸光度数据。
1.4 数据处理
使用自行编写的Labview程序(v2020, 美国国家仪器有限公司)对FL-LIBS光谱数据进行扣基线、读取平均谱峰信号及计算标准偏差等初步处理操作, 使用Origin 2024软件对数据进行作图处理。
2 结果与分析
收起
2.1 AAS方法评估
本研究采用常用的“3σ”方法计算LOD, 其表达式如公式(1):
LOD=3σ/S
式中: σ为噪音的标准偏差, 在本研究中取用Cr I 425.47 nm谱线附近的无分析信号的波长处的噪音信号进行计算; S为校准曲线的斜率。
以铬的质量浓度为横坐标(X, μg/mL), 吸光度为纵坐标(Y), 线性方程为Y=0.04636X+0.0064, 斜率S为0.04636, 回归系数为0.9993。经过15次空白试样(铝基底液)的测试得到空白的标准偏差值σ为0.00045, 计算AAS方法的铬的LOD为0.029 μg/mL。再根据实验步骤, 0.2 g铝样品溶解并定容至50 mL溶液中, 故可换算得样品中铬的LOD为7.2 μg/g。
2.2 FL-LIBS方法优化与评估
LIBS谱图会产生很高的连续辐射基线信号, 如图2中实线所示。过高的基线信号会对研究结果产生不利影响, 因此必须对实验结果进行扣基线优化处理。本研究采用YAROSHCHYK等[30]针对LIBS谱图开发的移动窗口最小值扣背景算法, 该算法因原理简单, 计算速度快, 处理效果好而被大量运用。其计算原理可用如公式(2)进行表示:
$B(i)=\sum_{j=1-w / 2+1}^{j=i+w / 2} \operatorname{Min}(j) \times \operatorname{rec}(i-j)$
式中: B(i)为最终拟合的背景曲线, i为谱图数据像素点序号, j为位于点i窗口处的数据像素点序号, w为移动窗口的长度(像素点个数), Min(j)为在该窗口内的数据最小值, rect(i-j)为方脉冲函数, 在窗口内的函数值为1/w, 而在窗口外的函数值为0。拟合结果如图2中虚线所示, 背景线很好地贴合了原始谱图的整体底部。扣除基线后的谱图如图3所示, 可以看出, 扣除背景后谱图基线整体十分平缓且接近于0, 说明扣背景效果良好。在该谱图中, 可以清晰找到铬原子的3条高强度特征谱线425.47、427.58和429.01 nm。为了获得更好的检测灵敏度, 本研究选用425.47 nm谱线的峰高作为分析数据来源。
本研究中所用激光器可以对脉宽和能量进行调节, 依据激光器技术说明书设置以上两个参数, 其相对制约关系如表1所示。在每个脉宽下分别设置其最高能量的30%、45%、60%、80%、100%进行参数优化探索, 结果如图4所示。从图4中可以看出, 在每个脉宽下信号随能量的增大而线性上升, 而取得最大信号的脉宽为200 ns, 故本研究使用200 ns、0.792 mJ作为后续实验条件。
从图5中可以看出, 虽然原始校准曲线的斜率较高, 但其回归系数仅有0.4945, 因此无法给出可靠的分析结果; 经过扣基线优化处理后, 斜率S为131599, 回归系数大幅提升至0.9435, 符合检测要求。另外还可以看出, 扣基线后信号的波动明显变小, 充分说明了扣基线优化的重要性。
经过计算, LIBS检测中的σ数值为25, 将其代入公式(1)计算, 可得本方法的LOD为5.7 μg/g, 优于本研究中AAS检测方法的7.2 μg/g。经检索, 同样使用LIBS方法检测铝合金中的铬的研究中的LOD结果均在10 μg/g以上, 如GRAVEL等[12]的10.8 μg/g、HE等[24]的62.7 μg/g、SABSABI等[31]的10.0 μg/g。可以看出, 本研究的LOD结果显著优于同类研究, 其中有些研究使用了高能激光(60 mJ)[31]。考虑到本研究中使用的激光能量较低(0.792 mJ), 该结果体现了本研究开发的FL-LIBS方法的优越性。
2.3 市售铝制食品包装样品检测结果对比
图6为可口可乐的LIBS谱图, 可以看到较为明显的Cr I 425.47 nm信号。将3种样品进行分析, 结果如表2所示。总体而言, 两种技术的结果相当一致, 其中, 铝箔纸和铝盒的LIBS/AAS结果十分接近, 而可口可乐的AAS结果明显偏高。可能原因为AAS样品前处理过程中将包装外表面涂层以及包装内的塑料性物质中的铬也消解进溶液中, 而LIBS只对内表面采样, 导致了AAS结果比LIBS高。由于直接与可乐接触的为包装内表面, 故对内表面进行采样更具实际意义。另外, LIBS分析中每个样本仅需耗时2 min, 而AAS检测全流程耗时4 h, 说明了本研究中LIBS技术的优越性。
3 结论
收起
本研究基于光纤激光诱导击穿光谱分析技术, 优化开发了一套铝制食品包装中铬的快速检测方法。该方法无需样品制备, 分析速度快, 成本低廉, 其LOD优于普遍使用的原子吸收分光光度法以及其他文献中报道的同类LIBS方法。使用两种方法对3种市售铝制包装材料进行检测, 总体结果吻合, 证明了本方法的可靠性。基于以上优点, 该方法有望应用于短时间内大量铝制包装样本的检测任务中。未来将进一步开发更多元素及更多样本材料的检测方案。
