ABSTRACT:
Onium species of nitrogen, phosphorus or sulfur are useful to precipitate ferric ion, existing as tetrahaloferrate anion, from strong haloacid solutions. The precipitants are useful in the field of well acidizing, because tetrahaloferrate anion attacks polymeric and viscoelastic surfactant thickeners used to thicken haloacid solutions.
