| 摘 要： | 以松花江水污染事件中硝基苯在河流滞水区和缓冲区中的沉降为背景,通过含硝基苯水体在实验室内的静置模拟试验,研究了含硝基苯的水体在低温条件下静置后硝基苯浓度的竖向分布规律。模拟试验的结果证实:当水体温度接近于0℃时,本试验浓度条件下静置水溶液中的硝基苯在溶液中均匀分布。 |

| Abstract: | To simulate the deposition of nitrobenzene in stagnant water and a buffer region of the Songhua River in pollution accidents, an experiment was carried out with nitrobenzene in static water. The vertical distribution of the nitrobenzene concentration was studied in static cold water. The results show that, when the water temperature drops to 0℃, nitrobenzene will exist in the solution homogeneously without deposition, although its specific gravity is higher than water and its melting point is higher than 0℃. |
