| Abstract ： | 「抄録」 生物試料などからのフッ素の分離には, 灰化・水蒸気蒸溜法がよく用いられているが, 非常に煩雑なことと, 大量の試料を必要とすること, あるいは, フッ素含有量の少ない試料の場合は, 溜取液を濃縮しなければならないことなど, 種々不便な点がある. これに対して, 微量拡散分析法の応用が注目され, いくつかの報告がみられている. 著者らは, エナメル質中のフッ素分離に, Conway型のセルを用いて微量拡散を行なう方法を追試・検討し, 十分な精度で, しかもごく簡易にフッ素を分離できることを確認した. |

| Abstract ： | For isolation of microgram amounts of fluoride in biological samples or mineral, dry-ashed and steam-distillation have been used well. However, these procedures are lacking in simplicity ; furthermore, in the isolation of fluoride from samples containing little fluoride, great amount of samples was needed or collected solution by distillation has to be boiled down to proper volume. Aa an another procedure for isolation of fluoride from various samples, microdiffusion technique hes been presented by Singer et al, Hall, Takaesu, Wharton and so on. The technique of microdiffusion using the polypropylene microdiffusion cell of Conway-type introduced by Wharton was studied in this paper : (1) The recovery of fluoride diffused from NaF (F. 5μg) solutions was studied : ... The temperatur necessary for this recovery was 60℃, and 18 hours was necessary. (2) The recovery of fluoride diffused from various content of fluoride solution (NaF) was studied : ... The time necessary for good recovery was 24 hours when the solution contains fluoride up to 30 μg. However, when the fluoride is above 40 μg, 48 hours were necessary for this recovery. (3) The recovery of fluoride diffused from typical dental enamel samples added NaF was studied, and favoreable and accurate result was obtained. |
