Simultaneous determination of hexafluorophosphate and other trace impurity anions in ionic liquids by ion chromatography

A method was developed for the determination of hexafluorophosphate by ion chromatography coupled with direct conductivity detection.

Application of phosphate ion controlled-release system in working electrolyte;

The immobilized yeast cells were embedded by the mixing carriers of sodium alginate-PVA,then dealed with phosphate ion which can intenerates and destroys the calcium alginate.

The retention mechanism of phosphate anion on an anion exchange column was studied.

The effect of the phosphate anion on the stabilization of hydrate in magnesium oxychloride cement(MOC) was investigated by the method of XRD.

Fluoridated hydroxyapatite films on glass and Ti alloy substrates were prepared by sol-gel technique using hexafluorophosphoric acid (HPF 6) as a fluorine-introducing reagent.

A process of preparing phosphorus pentafluoride was put forward: first, mesneproduct(hexafluorophosphoric acid) was prepared from phosphorus pentoxide and anhydrous hydrogen fluoride; second, phosphorus pentafluoride was acquired after dealing with the hexafluorophosphoric acid.
