Abstract
A method is proposed for modifying complex PAN fibre that allows obtaining a catalytically active Fe3+ complex on its surface; high strength of immobilization of the metal on the fibre support in the range of pH 4-12 is attained. It was found that active catalyst sites are formed due to the content of carboxylate-ion, amino, imine, and amide groups on the modified PAN fibre, and the metal is primarily distributed on its outer surface. The specific surface of the catalyst is determined. It is concluded that its nonporous surface causes catalysis in the outer diffusion region. The results of testing the catalyst at the factory of Wil'iam Baker Ltd. (Leicester, Great Britain) allowed recommending it for industrial use.
