Abstract:
A method of preparing aqueous hydrogen fluoride is provided. The method includes providing a composition including a cross-linked polymer with absorbed hydrogen fluoride. The cross-linked copolymer includes acrylamide units and acrylic acid salt units. The method further includes contacting the composition with water to release at least a portion of the hydrogen fluoride from the composition to the water to form the aqueous hydrogen fluoride.
