水中氨氮挥发影响因素探讨
A PRELIMINARY STUDY ON FACTORS INFLUENED THE VOLATILIZATION OF AMMONIA FROM WATER
-
摘要: 本文介绍了水中氨氮挥发的影响因素.水中氨氮挥发速率常数随水的pH值和水温升高而增加,水面风速大则常数值也大,大气压高的地区的挥发速率常数小于大气压低者.与蒸馏水体系相比,在实验条件相同时滇池湖水中氨氮挥发速率常数小.Abstract: Factors influenced the volatilization of ammonia from water to the atmosphere has been presented in this paper. The volatilization rate constants increase with increasing pHand temperature in water,and are larger in high wind speed above water surface than in tower wind speed. The constants are smaller in the region under higher atmosphere pressure than in the region of lower atmosphere pressure. In comparison with the distilled water system,the volatilization rate constans of ammonia from Dianchi Lake water are small under same testing conditions.
