ICP-MS分析汝瓷釉料中玛瑙和燧石的矿物元素

ICP-MS Analysis of Mineral Elements of Agate and Chert in Ru Porcelain Glazes

采用电感耦合等离子体-质谱法(ICP-MS)对汝瓷釉料玛瑙中17种矿物元素Al、As、Ba、Ca、Cr、Cu、Fe、Hg、K、Mg、Mn、Na、Pb、Se、Sr、V、Zn和燧石中14种矿物元素Al、Ba、Ca、Cr、Cu、Fe、Hg、K、Mg、Na、Pb、Sr、V、Zn进行分析测定.玛瑙中17种矿物元素的相对标准偏差为0.52%~4.58%,准确度范围为89.70%~101.03%;燧石中14种矿物元素的相对标准偏差为0.52%~4.40%,准确度范围为89.70%~101.03%.实验结果表明:玛瑙和燧石中Al、Ca、Fe、K、Mg、Na 6种矿物元素的含量均较高,其中,燧石中Fe的含量高于玛瑙中Fe的含量,玛瑙中其他5种矿物元素的含量均高于燧石中的含量.

17 mineral elements Al,As,Ba,Ca,Cr,Cu,Fe,Hg,K,Mg,Mn,Na,Pb,Se,Sr,V,Zn in Ru enamel agate and 14 mineral elements Al,Ba,Ca,Cr,Cu,Fe,Hg,K,Mg,Na,Pb,Sr,V,Zn in chert were analyzed and determined by inductively coupled plasma-mass spectrometry(ICP-MS).The relative standard deviations of 17 mineral elements in agate ranged from 0.52%to 4.58%,and the accuracy ranged from 89.70%to 101.03%.The relative standard deviation of 14 mineral elements in chert ranges from 0.52%to 4.40%,and the accuracy ranged from 89.70%to 101.03%.The experimental results show that the contents of 6 mineral elements such as Al,Ca,Fe,K,Mg and Na in agate and chert is higher,among which the content of Fe in chert is higher than that in agate.The content of other 5 mineral elements in agate is higher than that in chert.
