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.

Abstract: In order to remove fluorine from a zinc containing solution before zinc electro-refining in lower cost, fluorine is removed by adsorption from a zinc containing solution (leached solution) utilizing the character of the predetermined iron compound or zinc compound which can adsorb fluorine in an acid solution and desorb fluorine in an alkaline solution. The fluorine adsorbent/desorbent having adsorbed fluorine is treated in an alkaline solution, to desorb the fluorine. This makes it possible to regenerate the fluorine adsorbent/desorbent. Further, an electrolytic solution for zinc electro-refining can be prepared in lower cost, thus total zinc refining costs can be reduced.
