- 中文摘要:
The electrical migration of tetra-valent metal ions, Ge﹝IV﹞, Ti ﹝IV﹞, Zr﹝IV﹞, Th﹝IV﹞and U﹝IV﹞was observed by means of paper electrophoresis, using tartaric acid and tartrate or acetic acid and acetate buffers as background electrolytic solutions. These metals formed with the tartrate negatively charged complex ions which migrated toward the anode, but not with the acetate except the U[IV] ion, which was gradually oxidized to UO2+2 ion and then formed complexes with the acetate.
The ratio of ionic radii of tartrate complexes was approximately estimated from the ratio of their migration distances under the same conditions. - 英文摘要: --
