HYBRID SELECTIVE SORBENTS BASED ON ACETALS OF POLYVINYL ALCOHOL AND ACRYLIC HYDROGELS - article

Synthetic procedure has been developed and physicochemical properties (strength and elasticity, swelling degree and rate of swelling, as well as sorption capability) of hybrid materials based on polyvinyl alcohol acetal with porous space, partially impregnated by functional pH- and thermosensitive hydrogels was investigated. Synergetic improvement of the hybrid hydrogels has been displayed in comparison with the components they were constructed from, and perspectivity of using of these materials as selective sorbents for separation and recovery of the dye contaminated waste water, as well as their concentration and accumulation during sample preparation in analytical chemistry, especially for liquid and gas chromatography.

Keywords: hybrid hydrogels, selective sorbents, pH and temperature-sensitive hydrogels, concentration of samples, sorption of dyes
