Abstract
The present disclosure provides a method for processing a fluorine-containing aqueous solution. The method comprises a reaction step for mixing in a vertical direction the fluorine-containing aqueous solution and a disiloxane compound represented by a general formula RRRSiOSiRRR, wherein R, R, R, R, Rand Rare selected independently from each other from a group consisting of a phenyl group and an alkyl group comprising from 1 to 20 carbon atoms and hydrogen, to react a fluorine ion in the fluorine-containing aqueous solution with the disiloxane compound, obtaining a first reaction liquid containing a monofluorosilane compound represented by general formulas RRRSiF and RRRSiF.
