Phenomenon of Remote Interaction and Sorption Ability of Rare Cross-linked Hydrogels of Polymethacrylic Acid and Poly-4-vinylpyridine in Relation to Erbium Ions
Phenomenon of the long-range effect of poly(methacrylic acid) hydrogel poly(4-vinylpyridine) hydrogel (gPMAAgP4VP intergel system) оn erbium ions sorption was studied. It was established that the structure of the basic hydrogel had a significant impact on the self-organization of the PMAA hydrogel. The mutual activation of hydrogels was investigated in an aqueous medium. Dependencies of swelling coefficient, specific electric conductivity and pH of aqueous solutions were determined.
