基于ICP-MS的四川荥经砂器微量元素分析

利用电感耦合等离子质谱法(ICP-MS)对荥经砂器3种原料及成品进行了微量元素的测试分析,通过砂器原料中微量元素与一般土壤中微量元素含量的对比分析,以及人食物中的微量元素与砂器样品中微量元素的对比分析,重点对在4种样品中检测出的11种生命必需微量元素和11种生命毒性元素进行了研究.最后通过对比分析得出荥经砂器及原料中含有多种生命必需微量元素,且生命必需微量元素和毒性微量元素普遍低于一般土壤;按最大浸出量计算砂器中生命毒性元素含量大多数在人体正常范围之内.

Trace Elements Analysis of Yingjing Sand Pottery Based on ICP-MS Method

The trace elements test analysis on three raw materials and finished product of sand pottery of Yingjing was carried out by using ICP-MS method.By comparative analysis between the contents of trace elements in the raw materials of sand pottery and general soil,and between the contents of trace elements in the finished product of sand pottery and food,we mainly studied 11 kinds of necessary vital trace elements and 11 kinds of non-necessary vital trace elements.We found that there were many kinds of necessary vital trace elements in the sand pottery of Yingjing and the trace elements are mostly lower than normal soil.Most of the non-necessary vital trace elements content in the normal range and a few elements were beyond the normal range.
