Optimization of the operative conditions for heteropolyacids synthesis through ion exchange

Phospho-tungstic and phospho-molybdic Wells-Dawson heteropolyacids, H6P2W18O62 .xH2O and H6P2Mo18O62 .xH2O respectively, were synthesized through ion exchange with a higher yield (~ 90%) than the conventional organic route (~ 70%). Pure, non-degraded heteropolyacids are obtained when the correspondi...
