Description

一种塑料添加剂多组分高通量分析方法
本申请要求于2021年06月29日提交中国专利局、申请号为CN202110727339.1、发明名称为“一种塑料添加剂多组分高通量分析方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及塑料添加剂分析领域，特别涉及一种塑料添加剂多组分高通量分析方法。
背景技术
塑料添加剂是一类能够提高弹性、耐用性、延展性的化合物，广泛用于各种化妆品中，比如口红、指甲油等。常见的塑料添加剂包括：增塑剂、阻燃剂、紫外稳定剂、抗氧化剂等，目前有越来越多新兴的化妆品添加剂正逐渐取代传统的化妆品添加剂。有报道表明，接触邻苯二甲酸酯、对羟基苯甲酸酯和双酚类化合物塑料添加剂会对人类健康造成不良影响，包括内分泌紊乱、发育或生殖毒性。
消费者使用的口红和指甲油中可能存在多种会带来潜在健康风险的塑料添加剂。但目前关于口红和指甲油中塑料添加剂的研究通常仅针对单个或一类化合物进行独立评价，缺少关注多种塑料添加剂同时存在可能产生的复合效应，而且现有的分析方法大多耗时较长，且成本较高，因此亟需开发一种能够同时检测口红和指甲油中多种结构或用途各异的塑料添加剂的高通量且简便的前处理分析方法。
发明内容
本发明的目的是完善现有的口红和指甲油中塑料添加剂的分析方法，实现同时检测口红和指甲油中多种结构和用途各异的塑料添加剂，通过缩短分析时间，降低分析成本来提高分析效率。
本发明的目的通过以下技术方案来实现：
本发明提供了一种塑料添加剂多组分高通量分析方法，包括以下步骤：
(1)将待测样品与回收率指示物混合均匀；
(2)向步骤(1)所得混合液中加入含氨水的四氢呋喃溶液，振荡混合后超声至完全混匀；
(3)向步骤(2)所得混合液中加入甲醇水溶液，混匀后振荡、离心、浓缩，再过滤；
(4)向步骤(3)所得滤液中加入内标；
(5)采用超高效液相色谱-串联质谱联用仪对步骤(4)所得样品进行定量分析。
优选的，步骤(2)中，加入所述含氨水的四氢呋喃溶液后所得混合液为碱性。
进一步优选的，步骤(2)中所述含氨水的四氢呋喃溶液中含有0.1wt％氨水。
优选的，步骤(3)中所述甲醇水溶液中甲醇与水的体积比为3:1。
优选的，所述待测样品的用量为0.1g，所述含氨水的四氢呋喃溶液的用量为6mL，所述甲醇水溶液的用量为4mL。
优选的，所述步骤(3)为：向步骤(2)所得混合液中加入甲醇水溶液，混匀振荡后，从10mL的混合液中取2mL，在5000rpm条件下离心5min，然后在氮气流下浓缩至1mL，再通过0.22μm的有机滤膜过滤固体小颗粒。
在本发明中，步骤(3)中，所述从10mL的混合液中取2mL目的是稀释进样，因为口红与指甲油提取液会相对较稠，取部分样品可以减小仪器分析基质效应；所述离心优选在5000rpm条件下离心5min，所述离心的目的是沉淀加甲醇水溶液后析出的杂质。在本发明中，所述0.22μm的有机滤膜优选为美国VWR公司商业化产品，以1.5mL离心管中间加滤膜的形式实现，这种过滤膜的方式相对注射器结合滤膜，损失更小，并且不会引入背景污染。
优选的，所述待测样品为口红和指甲油中的一种或多种。
优选的，所述回收率指示物为目标待测物(塑料添加剂)所对应的同位素标记的化学物质，作用是校正前处理分析过程的损失。当化合物较多的时候，若无法满足所有化合物都有一一对应的同位素标准品，则同一类别的化合物可以用该类别中可以找到的对应的同位素标准品来校正。在本 发明中，所有回收率指示物为表1列出部分。
优选的，步骤(4)中，在电喷雾离子源负模式下所述内标为BPA-d16(双酚A-氘代d16)和tertbutyl paraben-d9(叔丁基对羟苯甲酸酯-氘代d9)，在电喷雾离子源正模式下所述内标为coumaphos-d10(蝇毒磷-氘代d10)。
优选的，所述含氨水的四氢呋喃溶液中，四氢呋喃与氨水优选采用不低于LC-MS级别的试剂，所述含氨水的四氢呋喃溶液优选现配现用，如配制500mL四氢呋喃(含0.1％氨水)，则先取499.5mL四氢呋喃，加入0.5mL氨水。超声步骤优选根据实际情况调整时间，因为此步骤受样品浓稠度、黏度影响。
优选的，所述甲醇水溶液中甲醇与纯水采用不低于LC-MS级别的试剂，如配制400mL甲醇水溶液(3:1，v/v)，则取300mL甲醇与100mL纯水混匀。

图2为不同前处理方法处理后目标化合物的加标回收率结果图。
具体实施方式
以下结合实例与附图对本发明的具体实施作进一步的说明，但本发明的实施方式不限于此。
实施例1：口红与指甲油中塑料添加剂多组分分析。
(1)试剂与材料
本实施例涉及到的目标物标准品共231种塑料添加剂，根据它们的分子结构特点或者用途将其分为七大类：①有机磷酸酯类(OPEs，n＝55)，包括有机磷酸酯三酯(organophosphate triesters)、有机磷酸酯二酯(organophosphate diesters)和有机亚磷酸酯(organophosphite esters)；②邻苯二甲酸酯类(PAEs；n＝41)，包括邻苯二甲酸二酯(phthalates diesters)和邻苯二甲酸单酯(phthalates monoesters)；③非邻苯二甲酸酯增塑剂(non-PAEplasticizers，n＝42)；④双酚及其类似物(BPs，n＝14)；⑤对羟基苯甲酸酯类(parabens，n＝6)；⑥紫外稳定剂类(UVs，n＝33)，包括苯并三唑(benzotriazoles)、苯并噻唑(benzothiazoles)、苯甲酮(benzophenones)和其他紫外稳定剂；⑦抗氧化剂类(antioxidants，n＝40)。这些目标物对应的同位素标准品共36种，其中33种作为回收率指示物(surrogate standards)，3种作为内标(Internal standards)，所有标准品购买自美国AccuStandard或加拿大Wellington实验室。目标化合物和同位素标准品的详细信息见表1。
本实施例使用的仪器主要有：液相色谱串联质谱联用仪(加拿大AB Sciex公司，型号5500Q-Trap)，氮吹仪(美国Orgnomation公司，型号12N-EvapTM)，离心机(湖南湘仪公司，型号L600)，旋涡振荡器(美国Scilogex，型号MX-S)。实验所用的四氢呋喃、氨水、甲醇、水、甲酸、乙酸铵为Optima级，均购买于美国Fisher Scientific公司。
(2)样品采集
本实施例分析的34支口红与15瓶指甲油样本均购买自网络知名品牌，所有样本保存在干燥避光条件下等待分析。
(3)样品前处理与仪器分析
取0.1g常温下保存的指甲油或口红，置于15mL玻璃离心管中，加入回收率指示物并混合均匀；加入6mL四氢呋喃(含0.1wt％氨水)，振荡混合后在水浴中超声至完全混匀(10min)；然后加入4mL甲醇水溶液(3:1，v/v)，混匀后振荡10min；从10mL的混合液中取2mL，在5000转下离心5min；在轻缓的氮气流下浓缩至1mL，通过0.22μm的有机滤膜过滤固体小颗粒，转移至1.5mL的样品瓶中，加入内标，再在高效液相色谱-串联质谱联用仪(UPLC-MS/MS)下检测，检测方法共8种，仪 器方法信息如表2、表3所示。
(4)质量保证与质量控制
本实施例采用了一系列的质量保证和控制程序来评价过程污染和基质效应。在样本前处理过程中，每7个样品至少设一个过程空白用于过程污染评价。过程空白(n＝8)中塑料添加剂含量较低，且浓度远低于口红和指甲油，最终浓度将扣除空白污染。在加标样本分析中，邻苯二甲酸酯和非邻苯二甲酸酯增塑剂的回收率为26～181％，有机磷酸酯为39～172％，双酚和对羟基苯甲酸酯为90～148％，紫外稳定剂和抗氧化剂为31～155％。口红和指甲油的回收率指示物的回收率为61～188％。每个目标化合物的定量限(LOQ)初始设定为其3倍信噪比(SNR)，然后根据LC-MS/MS分析与质量保证与控制结果进行调整，若计算的LOQ低于空白中的背景污染值，则使用最高空白浓度作为LOQ。最终所有塑料添加剂的检出限为0.53～1590ng/g(见表1)。
(5)分析结果
如图1所示，在231种塑料添加剂中，有44种化合物同时在口红与指甲油样品中检出率高于50％，口红中有47种，指甲油中有57种。在所有检出率高于70％的塑料添加剂中，对羟基苯甲酸酯类(Parabens)浓度(33.3％)占比重最大，高于非邻苯二甲酸酯增塑剂类(Non-PAE plasticizers，26.2％)、邻苯二甲酸酯类(PAEs，17.9％)，双酚及其类似物(BPs，7.1％)、有机磷酸酯(OPEs，5.6％)、抗氧化剂(Antioxidants，2.5％)和紫外稳定剂(UVs，0％)。
对比例1
选取了不同的前处理方法做基质加标实验进行了对比：
方法一为本发明方法，具体如下：取0.1g常温下保存的指甲油和口红各两份，置于15mL玻璃离心管中，其中一份指甲油和口红同时加入目标物和回收率指示物，另一份只加入回收率指示物，混合均匀后加入各6mL四氢呋喃(含0.1％氨水)，振荡混合后在水浴中超声至完全混匀(约10min)；然后加入4mL甲醇水溶液(3:1，v/v)，混匀后振荡10min；从10mL的混合液中取2mL，在5000转下离心5min；在轻缓的氮气流下浓缩至1mL，通过0.22μm的有机滤膜过滤固体小颗粒，转移至1.5mL的 样品瓶中，加入内标，待仪器定量分析；
方法二如下：取0.1g常温下保存的指甲油和口红各两份，置于15mL玻璃离心管中，其中一份指甲油和口红同时加入目标物和回收率指示物，另一份只加入回收率指示物，然后各加入1mL甲醇，室温下平衡30min，加入3mL二氯甲烷与正己烷体积比为3:1的混合溶剂，振荡20min后在水浴中超声20min，在5000转下离心5min后取上清液后转移至另一个15mL玻璃离心管，再加入3mL二氯甲烷与正己烷体积比为3:1的混合溶剂重复一次上述过程，第三次将加入3mL正己烷，振荡20min后在水浴中超声20min，在5000转下离心5min后转移上清液后，合并后10mL上清液在轻缓的氮气流下浓缩至1mL，通过0.22μm的有机滤膜过滤固体小颗粒，转移至1.5mL的样品瓶中，加入内标，待仪器定量分析；
分析处理后的结果如图2所示，方法一各种目标化合物的加标回收率集中在75％～120％之间，方法二回收率则比较分散，在25％～200％之间，且方法一的耗时比方法二短，综上所述，在符合标准的前提下方法一优于方法二。
