| Abstract: | Studies were carried out in a simulated river ecosystem for determination of volatile rates of 37 kinds of organic compounds. The results showed that volatile process of organic compounds was in line with first-order kinetics. Volatile rate constants were predicted with modified two-film mass transfer model. The predicted constant values approach the values determined practically. In addition, the 'methods for determining and estimating parameters have been introduced in this paper. |
