Abstract—A procedure for the preparation of a fibrous palladium-containing catalyst for the removal of dis-
solved oxygen from water was developed. This procedure includes the preliminary modification of an anion-
exchanger fiber with carboxylate ions, which makes it possible to localize metal clusters in a thin subsurface
layer of a fiber at the subsequent stages of the ion-exchange introduction of palladium into the carrier and the
reduction of palladium. It was found that the higher activity of fibrous palladium-containing catalysts based on
the citrate forms of anion exchangers, as compared with that of samples based on the chloride forms, was due
to the predominant arrangement of reduced metal clusters on the external surface and an adjacent thin layer of
the fiber.
