中文摘要:
      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,利用电感耦合等离子体发射光谱法测定其中的砷、铜、铁、铅、汞、镉六种微量元素,经加标回收测试,加标回收率在93.46—114.58之间,石墨炉-电感耦合等离子体法取得满意结果,该方法线性范围宽、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试且准确度和精密度高。
英文摘要:
      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.
