摘要
本文简要叙述天然水中的主要酸-碱反应和控制天然水pH的一些基本过程,包括各种均相和非均相的化学过程以及决定水体缓冲容量的主要机制.然后讨论如何用计算机处理的化学平衡模式估计和预测水体的缓冲容量以及对酸沉降的敏感性.其中介绍了化学平衡程序REDEQL_2应用于天然水体酸化缓冲容量研究的作用和方法.
Some primary acid-base reactions and pH-controlling processes including homogeneous and hetorogeneous chemistry and hydrogen buffer mechanism in natural waters are briefly described in this paper. Then how to use a computerized chemical equilibrium model to estimate and predict buffer capacity and susceptibility to acid precipitation of water systems are discussed . The paper recommends REDEQL-2 Chemical Equilibrium Program to being applied to acidified water on estimating buffer capacity. Therefor , the function and procedure in this scope are describe.
