This work describes a novel heterogeneous oxidation catalyst which is analogous to the homogeneous‐phase Fentons reagent for the successful destruction of a range of organic pollutants. The catalyst is a polyacrylonitrile fibre which was modified to incorporate ligatinggroups, resulting in a transition metal cation being firmly fixed onto the fibre. The novelty of the catalyst resides in its open‐knit mesh structure. In the presence of hydrogen peroxide, the catalyst containing ferric ions (as the active site) is shown to rapidly decompose phenol in addition to (a) the anthraquinone dyes: acid blue 45, carminic acid and reactive blue 19, and (b) the azo‐dye drimarine red K. B. The decomposition reaction was followed by ultraviolet spectroscopy, and the distribution of ferric ions on the external surface of the fibre was examined by a scanning electron microscope. The mechanical properties of the fibre were found to have decreased on modification but were still sufficient for the manufacture and commercial exploitation of the fibre.
