1、绪言近年来,关于起泡分离法在分析化学中的应用正在进行着大量的研究工作。这种方法也涉及到离子浮选法[1—4]、沉淀浮选法[5]、共沉淀浮选法[6—7]、吸附胶体浮选法[8、9]等分支。另外,与这些浮选法不相同、不须要生成浮渣或泡沫的溶剂浮选法,已有铟[10]、镅Ⅲ、铥[11]、铁[12]、(苯)酚[13]、甲基橙[14][15]的浓缩和浮选机理等报告发表。我们 1 Introduction In recent years, a large amount of research work is being carried out on the application of bubble separation in analytical chemistry. This method also involves the ionic flotation method [1-4], precipitation flotation [5], co-precipitation flotation [6-7], adsorption colloidal flotation [8,9] and other branches. In addition, unlike these flotation methods, which do not require solvent flotation to generate scum or foam, indium [10], 镅III, 铥 [11], iron [12] , Methyl orange [14] [15] concentration and flotation mechanism report published. we
