Interaction of β-cyclodextrin with mercury (II) nitrate
The interaction between β-cyclodextrin and mercury (II) nitrate has been studied using UV, IR and 1Н NMR spectroscopy, elemental analysis, and quantitative chemical analysis. The optimum conditions for complex formation were established. The binding constant for inclusion complex between β-cyclodextrin and nitrate ion of composition 1:1 was calculated. The formation of supermolecules of composition С42H70O35 · 3Hg(NO3)2 in a solution and on a surface of silica chemically modified with β-cyclodextrin was shown
