Addition of lanthanide ions to aqueous solutions of some methyl glycosides and 1,6-anhydrohexoses causes shifts of the signals in their p.m.r. spectra. The approximate location of the cation in the complexes was determined and an attempt was made to explain the shifts in terms of contact and pseudocontact interactions.

Related Compounds

Addition of lanthanide ions to epi-inositol and related compounds in aqueous solution causes shifts in their p.m.r. spectra which are interpreted as being due to diamagnetic, pseudocontact, and contactinteractions. The contact interactions show stereospecificity: they are greatest when the bonds connecting the protons to the cation form a planar zig-zag arrangement.

The article presents the results of research on reducing the concentration of heavy metals, such as copper and nickel, on natural zeolite in comparison with synthetic zeolite and chemically treated natural zeolite. The reduction of the content of specific types of heavy metals from aqueous solutions was investigated by the method of sorption kinetics. The results indicate the ability of natural zeolites to compete with synthetic zeolites.
