已观察到天然有机物（NOM）影响溴酸盐（BrO3-）的形成。特别令人感兴趣的是臭氧在低浓度环境溴的源水中的应用，以及NOM对溴生成的影响。以每升溶解有机碳（DOC）1毫克/升/毫克的O3剂量对14个水源水进行臭氧氧化。实验性的BrO3-浓度和臭氧暴露（OE）值（一个与美国环境保护局（USEPA）的病原体灭活Ct值等效的试验台标度参数）被用于提出一种方法，通过该方法可以估算任何给定OE的源水的BrO3-形成潜势。使用皮尔逊相关矩阵将实验结果与水质和运行参数进行关联，以研究NOM特性的影响。 使用DOC、UVA、SUVA、表观分子量和操作定义的分数对NOM进行表征。溴浓度、SUVA、OE、疏水性NOM百分比（HPO as%）和亲水性NOM百分比（TPI as%）与BrO3-的形成有很好的相关性，尽管没有观察到基于质量的单一NOM参数有很好的相关性。使用实验数据进行的强制回归分析产生了合理的模型，可以使用公用事业公司可能分析的参数来评估源水中的BrO3-形成。包括13个参考文献、表格、图表。

Natural organic matter (NOM) has been observed to influence bromate (BrO3 - ) formation. Of particular interest is the application of ozone to source waters with low concentrations of ambient Br - and the influences that NOM exerts onBrO3 - formation. Fourteen source waters were ozonated at an applied O3 dose of 1 milligram per liter per milligram per liter of dissolved organic carbon (DOC). Experimental BrO3 - concentrations and ozone exposure (OE) values (a bench-scaleparameter used as an equivalent to the USEPA Ct-value for inactivation of pathogens) were used to present a method by which BrO3 - formation potentials of the source waters for any given OE could be estimated. Experimental results were correlated with water quality and operational parameters using a Pearson correlation matrix to investigate the influence of NOM characteristics. The NOM was characterized using DOC, UVA, SUVA, apparent molecular weight, and operationally defined fractions. Bromide concentration, SUVA, OE, hydrophobic-NOM by percent (HPO as %) and transphilic-NOM (TPI as %) were found to correlate well with BrO3 - formation, though no single NOM parameter based on mass was observedto correlate well. A forced regression analysis using the experimental data yielded rational models to assess BrO3 - formation in source waters using parameters that may be analyzed by a utility.
