摘要:

The optimum pH for the formation of a chelate between Au(III) and 5-(p-ethoxyanilino)-5,6-dihydrouracil was found to be 6.2. The wavelength of maximum absorption was 520 nm. The pKa for the ligand was 4.32 and the molar absorptivity was 1,300. Interference studies were made. The chelate, in a solution of pH 6.0 to 6.5, can be quantitatively extracted by a 1:1 mixture (v/v) of CHCl3 and toluene.
