摘要：

The introduction of iodide (I(-)) has broad perspectives on the decomposition of perfluorocarboxylates (PFCAs, C(n)F(2n+1)COO(-)). However, the iodinated substances produced are highly toxic synthetic chemicals, hence, it is urgent to find a similar alternative with less toxicity. In this work, the defluorination of perfluorooctanoic acid (PFOA) by I(-), bromide (Br(-)) and chlorine (Cl(-)) was systematically compared in the VUV/sulfite process. Results indicated that the PFOA defluorination rates increased with increasing nucleophilicity of ha...
