Bench-Scale Magnetic Ion Exchange Practice for the Removal of Natural Organic Matter and Bromide from Estuarine Waters 从河口水中去除天然有机物和溴化物的实验室规模磁离子交换实践
发布日期: 2005-11-01
磁性离子交换树脂(MIEX)去除消毒副产物的性能 (DBP)前体和天然有机物(NOM)作为溶解有机碳(DOC) 对三个河口水域的溴离子(Br)进行了评估,反映了DOC和Br-浓度范围。 MIEX显示出非常快速的反应动力学和高的离子交换能力 低剂量总体上,DOC去除率为55-60%,DOC去除率为73-84%,DOC去除率为72-80% 溴离子。在所研究的各种竞争阴离子中,硫酸盐似乎具有 5分钟内去除率最高可达97-99%。腐殖酸和富里酸含量较高 通过MIEX处理去除,包括大部分DOC去除(55-60%)。包括2个参考文献、表格和图表。
The performance of a magnetic ion exchange resin (MIEX) in the removal of disinfection byproduct (DBP) precursors and natural organic matter (NOM) as dissolved organic carbon (DOC) and bromide ion (Br) was assessed for three estuarine waters reflecting a range of DOC and Br- concentrations. MIEX showed very rapid reaction kinetics and high ion-exchange capacity with a low dose and overall, provided 55-60% removal for DOC, 73-84% and 72-80% removal for bromide ion. Among the various competing anions examined, sulfate appeared to have the highest removal rate as high as 97-99 % within 5 minutes. Humic and fulvic acids were well removed by MIEX treatment and comprise most of the DOC removal (55-60%). Includes 2 references, table, figures.
