Electrochemical Removal of Bromide and It's Impact on Disinfection Byproducts 溴化物的电化学去除及其对消毒副产物的影响
发布日期: 2005-11-01
最近的一些研究表明,一项新技术可能具有 有可能降低饮用水源中的溴浓度。电解 用于将溴氧化成挥发性溴(Br2)。在pH值较高时,溴会水解成次溴酸或次溴酸盐 超过3.4。然而,在溴被氧化成溴的阳极上,水也可以被氧化 氧化成氢离子和氧,产生非常低的pH值和大量非常细的氧气泡,有利于溴而不是次溴酸盐。在这种情况下,溴会 挥发。在最近的研究中,这一过程已被证明能够消除 高达45%的溴化物来自加利福尼亚州水资源项目,这是一种污染源 加利福尼亚州4000万人的饮用水和一个可能产生非常严重后果的水源 溴浓度高。本文的目的是提出修改意见 为提高溴化物去除效率,对该工艺进行了改进。包括5个参考文献、表格、图表。
Some recent research has indicated that a new technology may have the potential to lower bromide concentrations in drinking water sources. Electrolysis is used to oxidize bromide to bromine (Br2) which is volatile. Bromine would hydrolyze to hypobromous acid or hypobromite at pHs greater than 3.4. However, at the anode where bromide is oxidized to bromine, water can also be oxidized to hydrogen ions and oxygen, producing a very low pH and significant volumes of very fine oxygen bubbles, favoring bromine over hypobromite. Under these conditions bromine will volatilize. In recent studies, this process has been shown to be able to remove up to 45% of bromide found the California State Water Project, a source of drinking water for 40 million people in California and a source that can have very high bromide concentrations. The objective of this paper is to present modifications to this process to increase bromide removal efficiency. Includes 5 references, table, figures.
