Abstract: | Polyaniline coatings of the cation-exchange resin Dowex and a synthetic composite material based on silica gel surface-modified by a sulfated styrene-divinylbenzene copolymer were prepared by precipitative polymerization of aniline on the surface of the supports. The optimal conditions for the preparation of the polyaniline-containing material providing the formation of a thin polymeric coating on the support surface were determined. Aniline is predominantly consumed to the formation of a uniform polymeric coating about 3 nm thick with an increase in the concentration of sulfo groups on the support surface. The efficiency of using the polyaniline-containing sorbents for the preparative isolation of DNA from plant tissue lysates was demonstrated. Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 6, pp. 1123–1130, June, 2007. |
