    摘要: The present technology provides compositions that are intimate mixtures of hydrogen fluoride and a polyacrylate-polyacrylamide cross-linked copolymer, as well as methods and preparing and using such compositions. The compositions are less hazardous and, therefore, more conveniently stored, transported, and handled in comparison to pure hydrogen fluoride. Further, the hydrogen fluoride may be readily recovered from the compositions of the invention for use.
