| preparation | ether acidification extraction method can be used to purify phosphotungstic acid. That is, industrial phosphotungstic acid is mixed with ether and divided into phases to obtain ether phosphotungstic acid complex, so that phosphotungstic acid is separated from impurity anions and impurity cations, and then the ether in the adduct is evaporated to obtain purified phosphotungstic acid crystals. |
| use | as biochemical reagent and chromatographic reagent |
