<P>PROBLEM TO BE SOLVED: To provide a method for treating hydrosilicofluoric acid-containing liquid capable of separating hydrosilicofluoric acid stably from liquid to be treated containing the hydrosilicofluoric acid. <P>SOLUTION: This method for treating hydrosilicofluoric acid-containing liquid for removing hydrosilicofluoric acid from liquid to be treated containing hydrosilicofluoric acid includes: an adsorption step in which the liquid to be treated is brought into contact with a weakly-basic anion exchange resin to allow the anion exchange resin to adsorb hydrosilicofluoric acid ion, and to thereby remove the ion from the liquid to be treated, and an elution step of eluting the ion thereafter. <P>COPYRIGHT: (C)2013,JPO&INPIT |
