用毛细管色谱在25℃测定了AuCl4、[Au(SO3)2]、[Au(CSN2H4)2]、[Au(CN)2]等配位体离子在HCl溶液中的扩散系数及AuCl4阴离子的扩散活化能, 并与文献中其它配阴离子的D值比较, 认为扩散离子的质量和所载电荷可能是决定配阴离子扩散系数的主要因素.

The diffusion coefficients of some of the Au(III), Au(I)-complexes and the diffusion activation energy of AuCl4- in HCl solution have been determine at 25癈 by capillary method. Analyzing the results obtained in combination with other published data, authors suggest that both the charge no. and mass of anionic metal-complexes may be the prime factors determing the magnitude of diffusion coefficient
