摘要：

An extraction system for the recovery of boric acid using 2-butyl-2-ethyl-1,3-propanediol (BEPD) as an extractant was studied. Loss of the extractant to the aqueous solution was lowered by using 2-ethylhexanol as a diluent. The extraction equilibrium of boric acid with BEPD was clarified, and the equilibrium constants for various diluents were determined. Furthermore, continuous operation for the recovery of boric acid using mixer-settlers for extraction and stripping was successfully conducted during 100 hours.
