[Flame atomic absorption spectrometry determination of zinc and ferrum in enamel].
The amount of zinc and-ferrum in enanmel was determined by flame AAS. For twenty six healthy men, the average of zinc and ferrum were 325.6 +/- 84.8 and 34.7 +/- 9.1 microg/g, respectively. For fifty four patients with dental caries disease, the average of zinc and ferrum were 269.9 +/- 63.5 and 38.7 +/- 10.0 microg/g, respectively. The difference between healthy men and patients of zinc and ferrum rate was insignificant. As to the determination method, the rate of recovery varied from 97.0 to 101.5% for zinc and from 97.2 to 102.4% for ferrum. The RSDs fo Zn and Fe are less than 2.60 and 2.10% respectively.
