Journal AWWA - Evaluating the Formation of Brominated DBPs During Ozonation AWWA期刊-评估臭氧氧化过程中溴化DBP的形成
发布日期: 1993-01-01
对含有溴离子的天然水进行臭氧氧化,会形成无机次溴酸盐和溴酸盐,以及许多溴化有机副产物,其中只有少数已被确定。本文所述的研究确定了溴仿、溴代乙酰腈、溴代乙酰酮、溴代乙酸和一组称为溴代醇的不稳定化合物。这些副产物对大多数用于稳定它们的淬火剂都有反应。低pH值、低碱度和低氨浓度有利于溶解有机溴(DOBr)的形成,并随着原水中溴浓度的增加而增加。溴的质量平衡表明,在某些情况下,已确定的DOBr含量小于10%。包括26个参考文献、表格和图表。
Ozonation of natural waters containing bromide ion leads to the formation of inorganic hypobromite and bromate and many brominated organic byproducts, only a few of which have been identified. The study described here identified bromoform, bromoacetonitriles, bromoacetone, bromoacetic acids, and a group of labile compounds referred to as bromohydrins. These byproducts are reactive toward most quenching agents used for their stabilization. Dissolved organic bromide (DOBr) formation was favored by a low pH, low alkalinity, and low ammonia concentration and increased as a function of bromide concentration in the raw water. A mass balance of bromide indicates that, in some cases, < 10 percent of the DOBr content has been identified. Includes 26 references, tables, figures.
