Abstract :
One-pot, microwave-assisted synthesis of various types of magnetically responsive materials from non-magnetic precursors has been developed. The preparation is based on the microwave irradiation of the suspension of the treated material with iron(II) hydroxide prepared by alkalization of iron(II) sulfate. Submicrometer magnetic particles formed during the microwave treatment deposited on the surface of the treated materials in the form of individual particles and their aggregates. The prepared magnetically responsive materials have been used as adsorbents for xenobiotics removal and as carriers for enzymes immobilization.
