Polymer inclusion membranes composed of poly(vinylidene fluoride-co-hexafluoropropylene) and trihexyltetradecylphosphonium chloride, or trioctylmethylammonium chloride: kinetics and isotherms of Cr(VI) removal
The kinetics and isotherms of Cr(VI) removal from sulfate solution by two polymer inclusion membranes (PIMs) composed of poly(vinylidenefluoride- co -hexafluoropropylene) (PVDF-HFP), as a polymer base, and trihexyltetradecylphosphonium chloride (Cyphos ® IL 101) or trioctylmethylammonium chloride (A...
