Process for separating ethan-1-hydroxy-1,1-diphosphonic acid from a solution thereof in an organic solvent in the presence of phosphorus oxyacids, characterized in that it comprises adding to said solution an alkali metal ion to form a monobasic salt of the etan-1-hydroxy-1,1-diphosphonic acid which is insoluble in the organic solvent and which forms a precipitate and then separates said precipitate from the solution.
