在滴汞电极上的扩散公式(Ilkovic,1934)提供用极谱法测定扩散系数的可能。Lingane曾研究金属离子在不同配位离子中扩散电流常数的变化,和比较金属离子与不同配位离子形成络离子后对扩散的影响。徐光宪等曾提出计算每一络离子扩散系数的基础式。至今尚未看到有关的完全处理和对各级络离子扩散系数的测定。本文尝试提出一种计算各级络离子扩散系数的方法,并以亚铊与乙酸根的各级络离子为例进行计算。
The diffusion formula at the drop mercury electrode (Ilkovic, 1934) provides the possibility of determining the diffusion coefficient by polarography. Lingane studied the changes in the diffusion current constants of metal ions in different coordination ions and the effect on the diffusion after the formation of complex ions between metal ions and different coordination ions. Xu Guangxian et al. Proposed the basic formula for calculating each complex ion diffusion coefficient. So far, no complete treatment has been observed and the determination of the coefficient of diffusion of various ions in the network has been made. This paper attempts to propose a method for calculating the diffusivity of complex ions at various levels. The calculation of each level of complex ions of thallous and acetate is given.
