Abstract
Evolution of swelling of gel-like strongly acidic resin and organic-inorganic composites based on this ion-exchanger was investigated. Non-aggregated nanoparticles of zirconium hydrophosphate were found to provide size invariability of the polymer pores, which contain functional groups (up to 20 nm), the nanoparticle aggregates squeeze these pores (down to 3 nm). Owing to this, the nanocomposite shows higher break-through capacity during removal of Ni2+ from water, than the sample modified only with aggregates.
