补充资料:离子浮选
      表面活性物质与溶液中的离子形成可溶性络合物或难溶沉淀物,附于气泡上浮,使离子分离的过程。这是从稀溶液中提取有价元素或消除废水中有害组分的一种有效方法,选择性好、选择效率和富集比高。1937年兰米尔(I.Langmuir)首先指出溶液表面上的硬脂酸能吸附溶液中的金属离子,50年代南非塞巴(F Sebba)发展了离子浮选,引起南非、日本、苏联等国重视。从70年代初开始逐步走上工业化。日本已成功地用于冶炼厂和选矿厂废水净化,提取铜、镉等有价元素,并净化印染厂的污水。苏联从冶炼厂废水中提取钨、钼。当废液含二价钼离子(Mo2+)0.1~1.0g/1时,可得品位为42~65%的钼产品,钼的回收率达90~95%,富集比达2000。此外,在处理原子能工业废水以及从海水中回收铀、锶等方面,也取得了进展。
  
  本法基本过程是用带有和将要浮出的离子(或离子络合物)相反电荷的异极性表面活性剂作捕收剂,加入水溶液中。捕收剂分子的极性端与溶液中要回收的离子互相作用,形成可溶性络合物或难溶沉淀物;捕收剂分子的另一端为疏水(亲气)的非极性基团,能附于从溶液底部吹入的气泡上,带至水溶液表面;再刮出分离。影响离子浮选效果的因素有:捕收剂的性能、pH值、气泡大小、气泡充入速度、浮选机特性、温度、老化效应、中性盐类、溶液浓度、泡沫稳定度等。离子浮选设备多为充气式的,类似浮选柱。
  
  离子浮选原则上可回收任何离子,缺点是捕收剂价昂贵,用量又较大,影响推广。70年代以来,在寻求廉价的捕收剂、捕收剂的再生以及浮选设备和控制技术等方面,有所进展。
