摘要: <正>泡沫分离是以气泡为介质,以组分的表面活性差为分离依据的一种新型分离方法,在许多领域得到广泛的研究和应用’‘”’。本文采用泡沫分离塔装置,以十二烷胺醋酸盐(DAAC)为表面活性剂去除电镀废液中的BFi。本法与目前国内采用的加温条件下化学吸附沉淀法相比,具有设备简单、操作简便、耗能低、处理量大等特点。

Abstract: A foam column was used for removing fluoborate anion. The removal rate of fluoborate anion was measured. It was found that Dodecylamineacetate (DAAc) could be used as a carrier, and its concentration, gas flowrate and pH value of the solution were some significant factors of the separation effect.
