Acme F

Acme F by ISE

General Methodology:

Fluorine was determined using 0.25-gram sample splits weighed into Ni crucibles.  One gram of sodium hydroxide was added and the mixture was fused at 600oC in a muffle furnace.  The fusion product was dissolved in 7 ml of deionised water and 5 ml of 30% sulphuric acid.  The solutions were transferred to plastic beakers and5 ml of 30% ammonium acetate added.  The volume was made up to 90 ml with deionised water.  The pH was tested and adjusted to 7.8 with either sodium hydroxide or sulphuric acid.  Fluorine content was determined using a fluorine selective ion electrode.
