近年来,浮选技术渗透到分析化学领域,已成为痕量元素分离富集的一种新的有效手段。它装置简单,能迅速简便地处理大量试样溶液,易于实现连续化和自动化,引起了分析工作者的注意。浮选作为分析化学的一种分离富集手段,是在溶液中通入气体,发生鼓泡现象,使其中存在的物质(离子、分子、胶体、固体微粒)吸附于 In recent years, the infiltration of flotation technology to the field of analytical chemistry, has become a trace element enrichment of a new and effective means. It is simple to install and can process large volumes of sample solutions quickly and easily, making it easy to achieve continuity and automation, drawing the attention of analysts. As a separation and enrichment method of analytical chemistry, flotation is a process in which gas is blown into a solution and bubbling occurs to adsorb substances (ions, molecules, colloids and solid particles) present therein
