Claim 0:
1. A method of removing perfluorinated compounds, the method comprising the steps of:
(a) providing a fluoropolymer material in a chamber;
(b) heating the chamber to a temperature in a range of 25° C. to 325° C.;
(c) providing an anaerobic environment in the chamber; and
(d) providing a fluorination gas in the chamber after step (c), thereby exposing the fluoropolymer material to the fluorination gas to produce a processed fluoropolymer material,, wherein the fluoropolymer material is in the form of pellets or powders,, wherein an amount of the perfluorinated compounds in the processed fluoropolymer material is less than 300 ppb,, wherein the perfluorinated compounds comprise perfluorooctanoic acid (PFOA) and an amount of the PFOA in the processed fluoropolymer material is less than 1.1 wt. % the amount of the PFOA in the fluoropolymer material, and, wherein the fluoropolymer material is a recycled fluoropolymer material.
