| 摘 要： | 为解决天然样品中元素的赋存状态及样品粒度对粉末法光谱分析的影响,本文根据苏联文献中的不完整资料,解决了设计上、材料选择上和工作条件选择上等一系列技术问题,重新设计制造了“电弧蒸发回收”装置。该装置采用电弧蒸发和静电集尘回收原理,使各种复杂的天然物质转变为简单的氧化物,回收物的粒径可达0.1μm以下。该装置不仅适用于中高含量范围,也适用于痕量元素样品的预处理。经该装置预处理的样品与撒样法和ICP粉末法相结合均取得了较好的分析效果。

| Abstract: | Aimed at eliminating the effects of occurence mode of elements and gran-ulity of samples on powder spectrometry, the authors, after consulting some incomplete information from Soviet literatures and solving a series of technical problems in such aspects as designing and material and working conditionchoosing, have developed an"arc evaporation recovery device". Based on the principle of electic arc evaporation and electrostatic dust-accumulation recovery, this device turns various complicated natural substances into simple oxid es, and thus can recover materials with diameter less than 0.1 μm. It not only can tackle the samples with moderate to-high element contents, but also suits the pretreatment of samples of trace elements. Relatively satisfactory analytical results are obtained for samples pretreated by this device in combination with either powder-spreading method or ICP powder method. |
