摘要： 采用电感耦合等离子体(ICP)结合质谱(MS)联用技术,对新疆乌苏天山泥火山土壤样品的金属元素组成及其含量进行测定。ICP-MS分析结果显示,未经任何处理的火山泥中K和Na的质量分数分别约为1.7%和1.5%,总碱金属的质量分数大于3.2%,Mg和Ca的质量分数分别约为0.9%和0.4%,总碱土金属的质量分数大于1.3%,说明未经处理的火山泥碱性、刺激性和腐蚀性较强;且其中的重金属元素Hg和Pb的含量均符合国家规范,As的含量略超过国家规范;未经过任何处理的火山泥中含有人体所需元素(Zn,Mn和Cu),符合《化妆品安全技术规范》(2015年版)中规定的总质量分数不能超过1%的国家标准,但含有《化妆品安全技术规范》(2015年版)中不允许含有的Cr和Cd,其中w(Cr)=69.14 μg/g,w(Cd)=0.28 μg/g。菌落测试结果表明,除菌落总数超过《化妆品安全技术规范》(2015年版)所要求的值外,粪大肠菌群、铜绿假单胞菌和金黄色葡萄球菌均未检出,霉菌和酵母菌总数低于国家标准。

关键词: 火山泥, 金属, 元素组成, 含量, 总菌落分析

Abstract: Inductively coupled plasma-mass spectrometry (ICP-MS) was used for the qualitative and quantitative analysis of metals in samples of mud from Xinjiang Wusu Tianshan volcano.ICP-MS analysis results showed that for the volcanic mud without any treatment,K mass fraction is 1.7%;Na mass fraction is 1.5%;total alkali metal mass fraction is more than 3.2%;Mg mass fraction is 0.9%;Ca mass fraction is 0.4%;and total alkaline earth metal mass fraction is more than 1.3%.The overall results indicate that the untreated volcanic mud is rather highly alkaline,irritant and corrosive;Hg and Pb mass fraction meet national health standards requirements;but mass fraction of As is slightly higher than national health standards.The results also showed that the total mass fraction of Zn,Mn and Cu is in line with the provisions of Safety and Technical Standards for Cosmetics (2015 ed),which is below 1% according to the national standards.In accordance with Safety and Technical Standards for Cosmetics (2015 ed),Cr and Cd are not allowed while the analysis results showed that Cr mass fraction is 69.14 μg/g,and Cd mass fraction is 0.28 μg/g.Overall microbial colony detection results showed that there are no fecal coliforms,Pseudomonas aeruginosa and Staphylococcus aureus in the sample and the total content of mold and yeast are not over than the provisions in the national standard.However,total number of colonies exceeds the provision in Safety and Technical Standards for Cosmetics (2015 ed).

Key words: volcano mud, metal, composition, content, total microbial analysis
