| 摘 要： | 含铜物料经盐酸-硝酸-氢氟酸混合酸在高压密闭容器中微波消解,电感耦合等离子体发射光谱法测定样品中的银、砷、铅、镉、锌、三氧化二铝、氧化钙、氧化镁、锰9种组分。对溶样试剂、微波消解条件、基体干扰进行了相关讨论。建立的溶样方法快速简单,矿样溶解完全;方法基体效应小,各待测元素之间没有明显干扰,待测元素回收率在93.3%～103.2%,方法测定下限在5～60μg/g,相对标准偏差(RSD,n=11)为0.5%～3.1%。使用建立的方法分析国家标准物质和实际样品,分析结果与标准值、其他常规方法测定值一致,在允许的误差范围内。与现行的分析方法相比,该法缩短了分析周期,适合大批量试样的分析,并已应用于实际的检验工作。

| Abstract: | The materials containing copper were prepared by microwave assisted dissolution in a pressurized vessel with a mixture of HCl-HNO3-HF.Nine components in sample solution including silver,arsenic,lead,cadmium,zinc,alumina,calcium oxide,magnesium oxide and manganese are determined by inductively coupled plasma-atomic emission spectrometry(ICP-AES).The sample could be quickly and completely dissolved.The effects of sample dissolving regents,microwave digestion conditions and matrix interference are discussed.Th... |
