PROPERTIES OF COMBINED SORBENT - 'ZEOLITE IN FIBER'

摘要

To employ the pulverized zeolites in dynamic conditions it was obtained the composite material - polyacrylonitrile fiber filled by natural zeolite powder - clinoptilolite-bearing tuff according to earlier developed methods. The ion-exchange and adsorption properties of the new combined sorbent, "zeolite in fiber", on the examples of sorption of Cu~(2+) from 0.5 N NaCl and of oil products from the waste water of car-washing stations, were studied. The distribution coefficients and diffusion coefficients of Cu~(2+) and the distribution coefficients of oil products on the sorbent were determined. It was shown that the ion-exchange rate of Cu~(2+) ions for the new sorbent increased considerably. The filtrating properties are very good. The sorbent is characterized by high selectivity to the oil products.
