Abstract
The possibility for the synthesis of a hybrid membrane incorporating a track membrane as a support and a layer of chitosan fibers modified by functional groups selectively sorbing cesium is studied. The layer of chitosan fibers is formed by electromolding. The surface of the nanofibers is modified by copper and potassium ferrocyanide immobilization. The structure of the nanofiber layer modified by copper and potassium ferrocyanide is studied by scanning and transmission electron microscopy and X-ray diffraction analysis. The specific pure water production capacity of the hybrid membrane is much lower as compared to the original track membrane. The data on the sorption capacity of the copper and potassium ferrocyanide layer on the surface of the nanofibers for cesium ions are correlated with literature data. The resulting hybrid membrane is suitable for the simultaneous selective sorption of cesium in the ionic and colloid forms.
