Abstract
Ferromagnetic hybrid polymers containing iron oxide deposit were obtained using sulfonic and carboxylic cation exchangers. The influence of ion exchange capacity, chemical constitution and porous structure of the polymeric matrix on the form and the quantity of iron oxide deposit was studied. Obtained materials contained the iron oxide load amounting to 9.0–23.0% Fe. The XRD, and IR and Mössbauer spectroscopic studies showed that hybrid polymers obtained using sulfonic cation exchangers contained mainly maghemite and magnetite within the polymeric matrix, while the inorganic deposit incorporated within the matrix of caboxylic cation exchangers was the mixture of iron oxide polymorphs (magnetite, maghemite, lepidocrocite, green rust and also Fe(OH)2). Due to high content of magnetite and maghemite deposited within the polymer matrix of the macroporous sulfonic cation exchanger this product showed highest magnetization saturation amounting 26 emu/g.
