Sulfocationates for water purification
Y. M. BilalovWe have carried the mechanical - chemical modification of polystyrene by BK, XBK, KBK, XAPP, and SXAPP and got sulfocationates on the basis of these polymer mixtures. The synthesized sulfocationates have the improved ion exchange capacity, swelling ratio, and mechanical durability indicators. There IR - specral analysis of the synthesized sulfocationates was carried out and new absorption lines of sulfogroups were appointed. The thermo gravimetric analysis of sulfocationates, got on the basis of mechanical - chemical mixtures PS: BK and RS: XAPP was carried out and it became clear that sulfocationates are thermostable within the temperature interval from 50OC up to 275300OC. Sulfocationates filled with mud was obtained and it was determined that they have improved indicators in comparison with industrial sulfocationate KU-2-8. It was determined that the synthesized sulfocationate characterized by the same technological indexes with KY -2-8 sulfocationate can be used in the purification process of industrial waters, but according to the mechanical durability indicator the suggested sulfocationate is more favorable in comparison with the KY-2-8 sulfocationate.
