A study of complex phosphovanadomolybdates [PVxMo12−xO40]−(3+x) by reversed-phase HPLC and capillary zone electrophoresis

A fundamental possibility of using ion-pair reversed-phased HPLC and capillary zone electrophoresis ( CZE ) for the study of polyoxometalate ( POM ) solutions has been demonstrated on an example of phosphovanadomolybdates of the composition [PV x Mo 12 − x O 40 ] −(3 + x ) , where x = 1–3 and the po...

Summary:A fundamental possibility of using ion-pair reversed-phased HPLC and capillary zone electrophoresis ( CZE ) for the study of polyoxometalate ( POM ) solutions has been demonstrated on an example of phosphovanadomolybdates of the composition [PV x Mo 12 − x O 40 ] −(3 + x ) , where x = 1–3 and the possibility of the separation of the products of their synthesis has been shown. It has been found that the modification of the inner surface of a capillary by alkyl groups C 1 and C 8 results in an increase in the resolution of analytical signals in CZE. It has been shown that the results obtained by HPLC and CZE are in a good agreement and can be confirmed by the data of 51 V NMR spectrometry.
