INTERACTION OF β-CYCLODEXTRIN WITH MERCURY(II) NITRATE

The interaction of beta-cyclodextrin with mercury(II) nitrate has been studied using UV, IR, and H-1 NMR spectroscopy, elemental analysis, and quantitative chemical analysis. The optimum conditions for complex formation were established. The stability constant of the 1:1 inclusion complex of beta-cyclodextrin and nitrate was calculated. The formation of supermolecules of composition C42H70O35 center dot 3Hg(NO3)(2) in solution and on a silica surface chemically modified with beta-cyclodextrin was shown.
