Composite ion exchanger, preferably for sorption of Sr-85, Co-60, Zn-65 radioisotopes and method for producing it

摘要

disclosed wymieniacz ion composite, especially to the sorption of radioisotopes sr 85, - 60, zn - 65, which is characterized by the fact that it is polikondensacyjna resin fenolosulfonowa built with fenolosulfonowego acid and formaldehyde as grains of spherical diameter from 00.01 to 0.25 mm, containing powdered sorbent competent, so sparingly soluble nanoparticles of titanium dioxide, in quantities of from 10 to 30 parts by weight.method of manufacturing composite an ion exchanger should, especially to the sorption of radioisotopes sr 85, - 60, zn - 65, is that the favourable early partially cross-linked acid fenolosulfonowego, at approximately 20u00b0c is 10 to 40 parts by weight of ditle nku titanium in the form of nanotubes, the mass obtained is added with formaldehyde solution again.and the suspension pours into the oil warm to temperature 90u00b0c by intensive mixing, at a rate of approximately 500 rpm. the mixture produced dyspersyjnu0105 diameter of between 0.01 - 0.25 mm, twardnieju0105cych within several minutes, creating hard spherical grains are separated by blotting, drought, temperature 100 degrees for about 1h, odtu0142uszcza organic solvent and then warm sorbent in temperature 60u00b0c.
