About swelling of hydrogels on base of pectin polysuccharides of sunflower baskets in water
There is summarized the result of study about the kinetic of swelling of hydrogels on base of pectin polysaccharide of sunflower baskets (SB) on wide area of changing pH the water solution. в широкой области изменение рН водного раствора. There are presented, also,the results of dividing the hydrogels into soluble and insoluble fractions for each rates of pH and duration of swelling. There is illustrated that in generally, process of swelling the hydrogels is going on neutral areas of pH, on acidic area the parallel reaction of swelling and extrations of Calcium ions from hydrogels matrix’s, and on alkaline areas-swelling and de-etherification. There is calculated rates of constant the swelling depending from pH and made a conclusion about nature of junctions the three-dimensional grid, formation of Calcium ions, hydrogen bonds of hydrophobic the interaction of chains copolymer the galacturonic acid.
