    Abstract: A salt of a divalent metal and a salt of a trivalent metal are added to a solution containing a fluorine compound and a fluoropolymer to precipitate a lamellar composite hydroxide containing the fluorine compound between lamellae and to simultaneously coagulate and precipitate the fluoropolymer suspended in the solution. Thus, a large proportion of the fluorine compound is fixed and separated from the solution together with the fluoropolymer. They are recovered according to need. By this treatment method, a fluorine compound and a fluoropolymer contained in wastewater or the like can be easily separated therefrom and the burden to be imposed on the environment or an ecological system can be lessened.
