石墨炉消解-电感耦合等离子体原子发射光谱(ICP-AES)法同时测定硫磺中6种微量元素

基于阿拉山口口岸重要地理位置,结合进口硫磺情况,收集阿拉山口口岸进口硫磺样品。采用石墨炉对硫磺进行消解,制备好的消解液利用电感耦合等离子体原子发射光谱法测定其中的砷、铜、铁、铅、汞、镉6种微量元素,计算元素含量,经加标回收测试表明加标回收率在93.5%～115%,测定结果满意,方法线性范围宽、检出限低、多元素同时测定、元素之间的干扰少、能适应不同样品的基体测定且准确度和精密度高。

Simultaneous Determination of 6 Trace Elements in Sulphur by Inductively Coupled Plasma Atomic Emission Spectrometry(ICP-AES) with Graphite Furnace Digestion

Based on Based on the important geographical location of the alashan pass port and the sulfur import situation, sulfur samples were collected at the alashan pass port. Of the sulfur by graphite furnace, using inductively coupled plasma emission spectrometry determination of arsenic, copper, iron, lead, mercury, cadmium, six kinds of trace elements, by the standard addition recovery test, the standard addition recovery rate between 93.46 114.58, graphite furnace - inductively coupled plasma method with satisfactory results, the method of wide linear range, low detection limit, determination of multiple elements at the same time, little interference between elements and can adapt to different samples of substrate test and of high accuracy and precision.
