Aplicação

Potassium fluoride may be used in thermodynamic analysis of DNA-ligand binding and studies on the structural stability of proteins and peptides.
A versatile fluoride ion source used in a study of ion-specific swelling and de-swelling of ampholytic polymer gels, in the room temperature oxidation of noble metals in HF, and in the measurement of electronic polarizabilities of ions in polymers of alkali halides.
