Abstract
To provide a good and simple method for decomposing and detoxifying a hardly decomposable fluorinated organic compound. Specifically, a fluorinated organic compound is decomposed by bringing an aqueous solution of the fluorinated organic compound into contact with a catalyst containing a metal oxide. The metal oxide may preferably be an oxide of at least one metal selected from the group consisting of Ni, Pd, Cu, Mn, Fe and Co, and more preferably be nickel oxide. The contact temperature is preferably within the range of from 0 to 100° C. Preferably, the fluorinated organic compound to be decomposed is an organic fluorocarboxylic acid, an organic fluorosulfonic acid or a salt thereof, which is used as a surfactant or an surface treatment agent.
