通过连续过滤方法和实验室氯化、臭氧化实验研究了哈尔滨地区土壤提取液中天然有机物的卤代活性以及不同形态天然有机物的差异 .比较了氯化和臭氧化条件下的卤代烃生成量及处理后的 7日卤代潜力 .研究结果表明 ,在数分钟的氯化实验中 ,憎水有机物、腐殖酸类化合物和非腐殖酸类亲水有机物的单位有机碳卤代烃生成量分别为 1 46、0 35和 4 0 3μg mg(C) .而 7日卤代潜力则分别为 6 6、5 7 2和 40 6 μg mg(C) .可见其差别不仅表现在热力学方面 ,而且反应在反应速率方面 .在本实验条件下 ,臭氧化能够降低大约水样的一半卤代潜力 Through continuous filtration method and laboratory chlorination and ozonation experiments, the haloactivities of natural organic compounds in soil extracts of Harbin and the differences of natural organic compounds in different forms were studied. The formation of halohydrocarbons under chlorination and ozonation conditions And the halogenated potential on the 7th after the treatment.The results show that in a few minutes of chlorination experiments, the hydrophobic organic compounds, humic acids and non-humic acid hydrophilic organic compounds per unit amount of organic carbon halogenated hydrocarbons Respectively, which were 146, 35 and 430 μg mg, respectively, while the halogenated potential on the 7th was respectively 6 6, 57 2 and 40 6 μg mg C. The difference was not only reflected in thermodynamics but also In terms of reaction rate, ozonation can reduce about half of the halogenic potential of the water sample under this experimental condition
