中文摘要:建立了金捕集-电感耦合等离子体质谱法同时测定电子烟气溶胶中铬、镍、砷、铅、镉、锑、汞7种重金属元素的方法。实验优化了电子烟气溶胶的捕集条件,采用含2.0 mg/L金元素的5.0%(体积比)硝酸溶液捕集吸收气溶胶,捕集阱为2瓶串联,每个捕集阱含吸收液25.0 mL,抽吸口数为100口。结果表明,电子烟气溶胶中的铬、镍、砷、铅、镉、锑和汞均能得到有效捕集。在优化条件下,铬、镍、砷、铅和镉的线性范围为0.3~80 μg/L,锑和汞的线性范围为0.3~10 μg/L,其相关系数(r2)均大于0.999,检出限为0.69~1.19 ng/100 puffs,定量下限为2.29~3.97 ng/100 puffs,方法的回收率为96.5%~103%,相对标准偏差(RSD)为6.6%~14%。使用该方法与法国标准方法对市售的10种电子烟样品进行测定,两种方法的检测数据基本一致。该方法准确、可靠、高效、使用试剂少,可用于电子烟气溶胶中多种重金属的检测。

Simultaneous Determination of Heavy Metal Elements in E-cigarette Aerosols by Inductively Coupled Plasma Mass Spectrometry
Abstract:A method of inductively coupled plasma mass spectrometry(ICP-MS) with Au solvent trapping was established for the simultaneous determination of 7 kinds of heavy metal elements,i.e.chromium,nickel,arsenic,lead,cadmium,antimony and mercury in e-cigarette aerosols.The trapping conditions for e-cigarette aerosols were optimized.The aerosols were trapped with dilute nitric acid solution(5.0%,by volume) containing 2.0 mg/L Au solution.Two impingers were tandemly connected,in which each contained 25.0 mL trapping solution,and the puffing number was 100.Results showed that,seven elements in e cigarette aerosols were trapped effectively.Under the optimal conditions,the calibration curves were linear in the range of 0.3-80 μg/L for Cr,Ni, As,Pb,Cd,and 0.3-10 μg/L for Sb,Hg,with their correlation coefficients(r2) larger than 0.999.The limits of detection(LODs) for seven elements were in the range of 0.69-1.19 ng/100 puffs,and the limits of quantitation were 2.29-3.97 ng/100 puffs.The recoveries ranged from 96.5% to 103% with relative standard deviations(RSD) of 6.6%-14%10 commercial e-cigarettes were determined by this method and the French Standardization,respectively,and the detection results were consistent.Therefore,this method was accurate,reliable,efficient and low-consumption,which could be used for the detection of heavy metals in e cigarette aerosols.
