| 摘 要： | 最近十几年来,海水物理化学中关于海水的化学热力学研究已较广泛地开展,并已有一些重要的研究结果报导。但是,关于海水中化学动力学的研究,至今却基本上仍属空白。然而这正是海洋中许多化学过程(特别像海水化学资源开发、海洋污染和防治等实践性比较强的领域中)要解决的关键问题。本文是我们从事这一方面研究工作的第一篇报导,讨论的内容是海洋中最重要的过程之一——无机离子交换过程。

| Abstract: | This article suggests a "filmprogressive model" for inorganic ion exchange in sea water,whose features are simplicity and ease of mathematical treatment.It has a good straight line relationship when experimental data are plotted into graphs and there is a quantitative relationship between it and B.A.M theory and its formulae.Using this mudel and mathematical equations it has been decided that the rate of ion exchange of uranium (Ⅵ) and hydrous titanium oxide and/or Aluminium-Activated Carbon composite exchanger throughout the whole process is controlled by film-diffusion.Experiments prove "film progressive model" is correct under conditions of minor components and in sea water.It is at Least as effective as B.A.M theory.This model will exhibit its theoretical guiding effect in the comprehensive utilization of marine resources,in marine pollution and prevention,in marine geochemistry of elements and suchlike spheres in so far as the study of kinetical problems are concerned. |
