砷是周期表中第四周期、第5主族、电子构型为3d~(10)4S~24P~3的元素,它可以从雄黄、毒砂矿中提取,但主要是在有色金属冶炼中作为副产品回收.由于砷的化合物具有剧毒的特性,在工业上又有重要用途,所以无论从环保或使用价值考虑,都应把含砷的物料加以处理与利用. 各国的生产、设计、科研及环保等部门对如何处理砷的问题非常关注.砷的提取和
Arsenic is the fourth cycle of the periodic table, the fifth main group, the electronic configuration of 3d ~ (10) 4S ~ 24P ~ 3 elements, it can be extracted from realgar, arsenopyrite mine, but mainly in non-ferrous metal smelting As a by-product recycling. As arsenic compounds have highly toxic properties, in the industry has another important use, so both from the environmental or use value considerations, should be treated with arsenic-containing materials and use of various countries in the production, design, research And environmental protection departments on how to deal with the issue of arsenic is very concerned
