从1912年以来,矿山工业上就已广泛采用浮选的方法,进行颗粒物料的选矿。在1937年Langmuir等发现用浮选方法提取离子的可能性。1959年Sebba首先使用了离子浮选法从水溶液中,选择性地分离多种离子。近十几年来,在分析化学中,有关浮选分离及浮选—吸光光度法的综述及评论,已发表很多。浮选分离技术能从极稀的溶液中,简便、有效地分离富集痕量物 Since 1912, flotation methods have been widely used in the mining industry for beneficiation of particulate materials. In 1937 Langmuir et al. Found the possibility of extracting ions by flotation. Sebba first used ionic flotation in 1959 to selectively separate multiple ions from aqueous solutions. In the past ten years, in analytical chemistry, the review and comments on flotation separation and flotation-absorbance spectrophotometry have been published. Flotation separation technology from the very dilute solution, simple and effective separation of trace enrichment
