Immobilisation of iron ions on nafion® and its applicability to the photo-fenton method

Immobilisation of iron ions on Nafion® is a promising technique to perform the Photo-Fenton method in a neutral pH range. Nafion® fulfil the requests of being a good complexing agent for iron and it is stable under oxidative and aqueous conditions. The efficiency of this new photocatalyst has been demonstrated by degradation experiments of 4-chlorophenol. In addition the influence of thickness and area of the membrane on the TOC reduction was tested. Reusing of the membrane after a specific treatment sequence described in this work is also possible and the photocatalyst showed resistance to ageing.
