| 内容記述 | Separation is necessary to the determination of fluoride in most types of biological samples except bone and teeth. At present, the diffusion procedures have widely used because many samples can be dealt with at one time and high temperatures are not required. In 1967 D. R. Taves discovered that diffusion of fluoride was greatly accelerated by the presence of silicone grease containing acidified sample and led to the development of a new procedure for rapid diffusion of fluoride at room temperature, using hexamethyldisiloxane (HMDS). Consequently, we studied several conditions concerning acidified samples containing HMDS in diffusion. Diffusion bottle on the market (Tupper Ware Minicup) was used and filter paper (12×25 mm) was hanged for trapping of fluoride. The results of several experiments are summarrized as follows: 1. As trapping solution 0.5 M sodium hydroxide was effective in fluoride recovery rate compared with 0.5 M magnesium succinate. 2. The concentration of perchloric acid for evolution of fluoride ranging 2.7 to 2.7×10^<-2>M makes no difference in recovery of fluoride. 3. HMDS in sample solution shortened the diffusion time. In addition to that, shaking of diffusion bottle shortened the diffusion time up to 30 to 60 minutes at room temperature. | |||||||
