摘要

经过处理的天然水中的溴会被臭氧氧化成有毒的溴酸盐。鉴于脉冲电晕放电（PCD）在水处理中的新颖性，它在溴化物转化中的潜力需要得到澄清。对溴-溴酸盐转化取决于控制参数（包括脉冲重复频率、pH 值、溴浓度和有机物的存在）的实验研究已经展开。在酸性和环中性介质中，溴转化为溴酸盐；还观察到溴酸盐转化为溴化物。溴化物在碱性介质中的氧化程度很低。草酸盐阻碍了溴的氧化。溴酸盐明显减缓了硝酸盐的形成。

Aqueous bromide oxidized with pulsed corona discharge

Bromide in treated natural waters is oxidized to toxic bromate with ozone. For the novelty of pulsed corona discharge (PCD) in water treatment, it's potential in bromide transformation needs clarification. Experimental research into bromide-bromate conversion dependent on control parameters, including pulse repetition frequency, pH, Br⁻ concentration, and presence of organics, was undertaken. Bromide transformed to bromate in acidic and circum-neutral media; transformation of bromate to bromide was also observed. Bromide was poorly oxidized in alkaline media. Oxidation of bromide was obstructed with oxalate. Formation of nitrate was noticeably decelerated by bromate.
