以H2O-Br--Cl2/NH2Cl/ClO2为研究对象,考查UV作用下BrO3-产生的情况。结果表明:原水和去离子水背景下,Cl2/UVC联用可以氧化部分的Br-生成BrO3-;NH3可以有效的抑制BrO3-生成,并且NH2Cl/UVC作用时不生成BrO3-;ClO2/UV体系产生溴酸根能力明显弱于Cl2/UV;ClO2/UVC产生BrO3-的量高于ClO2/UVA。酸性条件同时促进BrO3-的产生和ClO2的分解,碱性条件正好相反。
The effect of UV irradiation on bromate (BrO3-) formation is investigated in H2O-Br--Cl2/NH2Cl/ClO2 systems. It is found that partial bromide ion was oxidized to BrO3- by Cl2/UVC. NH3 can inhibit the forming of bromate effectively
and no production of bromate is observed by NH2Cl/UVC. The bromate formation capability of ClO2/UV system is weaker than that of the Cl2/UV. Furthermore
the amount of bromate produced in ClO2/UVC is larger than that in ClO2/UVA. Both the formation of bromate and the decomposition of chlorine dioxide are improved in acidic conditions
whereas alkaline conditions lead to reverse effects.
