硬软酸碱原理是六十年代美国化学家R.C.Pea-rson首先提出来的,十多年来获得了迅速的发展,并被应用到有关学科领域中。但是,迄今在地球化学中见到的有关应用这一原理的报导为数甚少。本文试图根据硬软酸碱原理,针对地球化学中的若干问题进行初步分析,作为进一步研究有关问题的参考。硬软酸碱原理是以广义酸碱理论为基础而发展起来的,在讨论问题之前首先对广义酸碱理论及硬软酸碱概念作一简略介绍。
Hard and soft acid-base principle was first proposed by American chemist R.C.Pea-rson in the 1960s and has been rapidly developed over the past decade and has been applied to related disciplines. However, there have been few reports on geochemistry that have hitherto been applied to this principle. Based on the principle of hard and soft acids and bases, this paper tries to analyze some problems in geochemistry, as a reference to further study the related problems. Hard and soft acid principle is based on generalized acid-base theory and developed, before discussing the issue of generalized acid-base theory and hard and soft acid and alkali concepts for a brief introduction.
