- Abstract
A commercial crosslinked ionic polymer AV-17 containing N(CH3)3Cl groups was used. The common compounds of Bi(III) and Al(III); Bi(III) and Cr(III); Bi(III) and Fe(III); Bi(III) and FeOOH and of three components-Bi(III), Fe(III), and Cr(III); Bi(III), FeOOH, and Cr(III) were obtained in the AV-17 polymer phase and investigated using scanning electron microscopy, powder X-ray diffraction, thermogravimetric analysis, and Fourier-transform infrared spectroscopy. It was shown that metal-containing compounds were concentrated on the surface of the polymer granules. The compounds were in the crystalline (BiOCl) or amorphous (jarosites and oxihydroxides) state. The morphology and composition of the metal-containing ultra dispersed particles were different on the surface and in the volume of the polymer granule. Most of the metal-containing compounds were in the form of pseudo spherical particles, but compounds containing Bi(III) and FeOOH in the volume of AV-17 granule, were in the form of clew of nanometer fibers. Thermogravimetric analysis (in an N2 atmosphere) in the range 24-1000°C of the metallic compounds containing polymer was also carried out. The metal-containing polymer samples were stable up to 120°C. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
