실험 절차
Hydrated hafnium-ammonium-ascorbate was prepared as follows: 1.6 grams of hafnium-tetrachloride and 1.86 grams of crystalline ascorbic acid were dissolved in 5 ml of water, and the pH was adjusted to 6.5 with ammonium hydroxide. Two ml portions of the resulting solution were administered orally to rats and radiographs were obtained comparable to those seen with preparations described in the previous examples. Soluble complexes of ascorbic acid and hafnium possessing similar properties were obtained using molar ratios of ascorbic acid to hafnium of from 1:1 to 4:1.
