一、前言在分析化学中,浮选分离法像常用的有机试剂萃取法、吸附法、共沉淀法、色谱法、电化学等方法一样,是一种分离、富集痕量元素的新方法。该法应用于分离元素还只有十来年的历史,但已对分离稀溶液中金属和非金属离子、络合物、蛋白质、微量有机物和微粒等作了广泛地研究。实际应用表明,此项分离技术可以从极稀溶液中(10~(-1)克分子/升)分离和富集超微量元素。除适用于工业污水、海水等水质分析外,很适用 I. Introduction In analytical chemistry, flotation separation is a new method for separation and enrichment of trace elements, like the common organic reagent extraction, adsorption, coprecipitation, chromatography, and electrochemical methods. This method, which has been used for the separation of elements for only ten years, has been extensively studied for the separation of metallic and non-metallic ions, complexes, proteins, trace organics and microparticles in dilute solutions. The practical application shows that this separation technology can separate and enrich ultra trace elements from very dilute solution (10 ~ (-1) mol / l). Except for industrial wastewater, sea water and other water quality analysis, it is applicable
