| Abstract: | Analysis of highpurity lithium fluoride for use with the manufacture of optical fibers were studied. The sample is dissolved in HNO3 , heated to dry for removal F- , the remainder is dissolved in H2O and HNO3 , then transitional metals Fe,Co,Ni,Cu in the solution are determined by GF AAS. In the sample Fe,Co,Ni,Cu are all less than 0.0001% with relative standard deviation 42%16.8%8.8% and 6.9% respectively. |
