The Developing of the Anodizing Process for the Preparation of the Plate Source of Nonmetal Nuclide

To develop anodizing devise of 20% sulphuric acid for the preparation of the source of nonmetal nuclide, the process paramenters of the anodizing membrane were studied, the adsorption performance of radionuclide ¹⁴C was verified, and a new method for the preparation of the plate source of nonmetal nuclide was developed. The influence of several parameters including temperature, volt and time to the thickness of the anodizing membrane were investigated within 14-20 ℃, 10-22 V and 20-150 min. The result shows that the thickness of the anodizing membrane produced by the process is within 4-60 μm and the uniformity of the thickness is precede 7%. The absorbent of the anodizing membrane within 4-12 μm is over the 75% to the ¹⁴C. The research can provide a new method for the developing of the plane source of nonmetallic nuclide.
