葡萄酒中稀土元素的测定

摘要：选用三种典型葡萄酒（红葡萄酒、白葡萄酒和起泡酒），采用湿法消解进行样品前处理，用ICP-MS对其中的稀土元素进行测定，各元素的检出限分别为La 0.0028 μg/L、Ce0.0034μg/L、Y 0.0018 μg/L、Pr 0.0010 μg/L、Nd 0.0037 μg/L、Sm 0.0026 μg/L、Eu 0.0009 μg/L、Gd 0.0019 μg/L、Tb 0.0004 μg/L、Dy 0.0011 μg/L、Ho 0.0003 μg/L、Er 0.0012 μg/L、Tm 0.0003 μg/L、Yb 0.0010 μg/L、Lu 0.0003 μg/L、Ge 0.0065 μg/L、Sc 0.2431 μg/L，三类葡萄酒样品进行三个水平添加回收率在92.0%-106.3%之间；相对标准偏差在0.49%-8.60%之间。本方法快速准确，可用于葡萄酒稀土元素的测定。

稀土元素是指元素周期表中原子序数57-71的15种元素以及钪（Sc）和钇（Y）共17种元素。我国是稀土储藏、生产及应用大国，葡萄种植土壤中会有一定量的稀土元素，同时由于稀土元素对植物的生长具有促进作用，被广泛运用到种植业，通过植物迁移作用，进入到植物体内，葡萄酒通过葡萄酿制而成，酿酒葡萄受到品种、土壤、气候以及所施肥料的影响，其元素特性会迁入到葡萄酒中，再加上葡萄酒的酿制过程需要用到硅藻土等，也会带进无机元素，有研究表明葡萄酒中稀土元素含量具有表征其地理标志的作用。
随着电感耦合等离子体质谱仪不断迅速发展，凭借其背景低，灵敏度高的特点，样品经直接消解进入检测系统，不需要富集分离就可达到ppd级的检出限，在稀土元素的检测中独居鳌头，难以替代。我们在葡萄酒的检测过程中研究建立了葡萄酒稀土检测的电感耦合等离子体质谱法，不仅能为葡萄酒中影响人体健康的稀土元素含量提供有效的检测结果，同时检测结果还可以为葡萄酒地理标志乃至于甄别其真假提供数据依据。
实验部分
1、实验材料
1.1 葡萄酒样品市售红葡萄酒、白葡萄酒、起泡酒
1.2 试剂：硝酸（优级纯）；
稀土元素标准溶液（100mg/L）（加拿大SCP分公司）

2方法的建立
2.1前处理方法的选择及优化
2.1.1消解方式的选择
参考相关葡萄酒元素测定以及植物性食品稀土元素检测的样品处理方式，针对葡萄酒含有酒精和其他有机质的特点，主要是从消除酒精，消化有机质两方面重点切入。参照葡萄酒中元素检测的前处理方法（GB/T15038-2006 葡萄酒、果酒通用分析方法中铜、铁测定的处理方法，直接稀释法和酸消解法，通过实验我们发现由于葡萄酒基质的影响，直接酸稀释法检测结果不稳定，加标回收率也不理想,如果采用基质匹配法配制标准溶液，难以找到合适的基质，特别是其中的有机质容易在锥上积碳影响仪器的使用寿命和检测的稳定性，选用酸消解法进行样品前处理，结果非常理想，基本消除了基质的影响。(见表1）。

2.1.2消解试剂的选择
参照GB 5009.94-2012 植物性食品中稀土元素的测定中样品处理方法，结合葡萄酒的特殊性，如果直接用酸进行消解，由于酒精的存在，会使反应异常剧烈，因此我们选择在100℃（酒精沸点78.3℃）进行低温加热挥发，待溶液挥发三分之二后，冷却加酸消解。
硝酸是一种强氧化性酸，为食品无机分析最主要的消解试剂，可以有效的分解大多数食品样品，目前成为较好的食品消解试剂，同时，由于其产生的质谱干扰小，被认为是ICP-MS分析最好的酸介质，因此，我们选取硝酸作为消解酸。检测中未发现酸介质干扰。
2.4 消解试剂用量的选择
我们本着保证完全消解样品，尽量减少消解试剂用量的原则，结合其他方法选用的试剂用量，分别选取0mL、3mL、5mL、8mL和10mL对添加量10μg/L的样品进行进行实验，结果见表2。

从实验中可以看出，不加入酸，检测回收率差于加酸消解，3-10mL硝酸量相对于本实验选取的样品，回收率影响不大，通过本实验结合其他标准方法选取的消解试剂用量，我们选取5mL硝酸作为消解样品消解液的用量。酒精挥发酸消解相对于有文献报道的微波消解方法，我们认为更具安全性，在时效上也不输于微波消解法，是一种更经济适用的样品处理方法。通过实验证明，方法的回收率和稳定性都非常理想。
3.1仪器测定条件
按照仪器操作规程用多元素调谐液优化仪器，使其背景值、稳定性、氧化物、双电荷、灵敏度、分辨率等参数达到仪器要求。
使用稀土标准溶液优化雾化器流量、RF功率。我们使用的仪器分析条件为射频功率1500W；等离子气流量载气流量为0.94L/min；辅助器流量为1.2L/min；等离子气流量为15L/min,；透镜电压5.5V，采样流量0.8mL/min。
3.2 基体干扰及消除
机体干扰主要来源于样品的机体，对待测元素产生增强或抑制作用，产生系统偏差。选择适当的内标元素能有效的克服机体效应，内标元素选择我们遵循：样品中不含的元素；不受样品中基体及分析物的干扰；与待测元素质量相近电离能相近原则。在常作为内标元素的元素中我们选取Rh 的质量数为103电离能为719.7与大部分稀土元素质量数和电离能相近，作为内标元素。
