Conclusions
-
1.
From the17O,27Al,71Ga, and183W NMR spectra, we have established that the structure of heteropolyanions of dissolved heteropoly compounds K3[Al(OH)6;Mo6O18], K3[Ga(OH)6Mo6O18] and H5[GaW12O40] is retained in aqueous solutions.
-
2.
The27Al(71Ga) NMR spectra are sufficiently characteristic for identification of anions of hexamolybdate and dodecatungstates of aluminum (gallium) in aqueous solutions.
