Abstract: New composite adsorbent based on modified polyacrylonitrile fibers is synthesized by in situ deposition of potassium-nickel ferrocyanide layer on the fibers’ surface. It is shown that the ferrocyanide phase forms a compact homogeneous layer on the fibers’ surface consisted of rounded nanoaggregates (∼ 40 - 50 nm). Composite fibers are chemically stable in both acidic and alkaline solutions. Sorption experiments have demonstrated that synthesized fibers are high-selective adsorbents and can be used for the purification of natural waters and high-salt solutions from cesium radionuclides.
