臭氧氧化过程中羟基自由基（HO）和溴酸盐的形成受到强烈影响 受水质和处理变量的影响。HO的量化^{CT值确定，表示为HO的比率暴露（或 臭氧暴露（或浓度）。进行了两个阶段的R_CT 在整个臭氧氧化过程中，R_CT的值在任何特定时间都保持不变 处理一组水质。 各范围之间存在线性关系 水质参数和HO溴酸盐形成的浓度或速率。溴酸盐 可以通过添加酸或氨来抑制中间体OBr-来控制生成。 将水的pH值从环境（8.2）降低到7.5和6.5的酸添加量会减少溴酸盐 形成率分别为30%和80%。相比之下，添加氨水可以降低成本 在pH值为7.5和8.5时，溴酸盐的生成率分别高达60%和85%。随着水的pH值降低，氨水减少溴酸盐生成的效率降低。 包括7个参考文献、表格、图表。}

Formation of hydroxyl radicals (HO^.) and bromate during ozonation is strongly influenced by water quality and treatment variables. Quantification of HO^. was determined by introducing the R_CT value, expressed as a ratio of HO^. exposure (or concentration) to ozone exposure (or concentration). Two phases of R_CT were performed and the values of R_CT remain unchanged at any specific time throughout the ozonation process with a set of water quality. Linear relationships were observed between extents of water quality parameters and HO^. concentration or rate of bromate formation. Bromate formation can be controlled by adding acid or ammonia to depress intermediate OBr^-. Acid addition to lower water pH from ambient (8.2) to 7.5 and 6.5 reduced bromate formation by 30% and 80%, respectively. In comparison, adding ammonia reduced bromate formation up to 60% and 85% at pH 7.5 and 8.5, respectively. Ammonia's efficiency to mitigate bromate formation was lessened with lowered water pH.
