本研究的目的是评估一种磁性离子交换树脂用于 作为消毒副产品控制的天然有机物和溴化物的去除 技术加州四家公用事业公司的原水采用磁离子处理 交换树脂，然后用明矾凝固。进行了一组平行实验 单独用明矾凝固法进行。对原水和处理后的水进行了分析 总有机碳和溶解有机碳、254 nm处的紫外吸收率、溴和 三卤甲烷和卤乙酸的生成潜力。水也是如此 在处理前后分馏，以确定分子量分布和 溶解有机碳的疏水/亲水特性。包括18个参考文献、表格、图表。

The objective of this research was to evaluate a magnetic ion exchange resin for the removal of natural organic matter and bromide as a disinfection byproduct control technology. Raw waters from four utilities in California were treated by the magnetic ion exchange resin followed by coagulation with alum. A parallel set of experiments was conducted with alum coagulation alone. The raw and treated waters were analyzed for total and dissolved organic carbon, ultraviolet absorbance at 254 nm, bromide, and trihalomethane and haloacetic acid formation potential. The waters were also fractionated before and after treatment to determine the molecular weight distribution and hydrophobic/hydrophilic character of the dissolved organic carbon. Includes 18 references, tables, figures.
