采用DAX-8吸附树脂三柱、AG-MP-50阳离子树脂柱、WA10弱阴离子树脂柱依次分离低DOM水(<5 mg/L)中的溶解有机物(DOMS)。然后将该程序应用于在新泽西州中部两个地表水处理厂(WTP)的不同取样点获得的分级水样，以研究其有效性、DOM的发生以及随着处理单元的变化。处理厂使用不同的处理方法，因此产生适合于检查该程序有效性的DOM组分的可变性。将该方法与现有的分馏方法进行了比较，证明了该方法对低DOM水的分馏是准确的。
A technique to fractionate dissolved organic materials (DOMs) from low DOM water (<5mg/l) was developed by using triple columns of DAX-8 adsorption resin, one column of AG-MP-50 cationic resin, and another column of WA 10 weak anionic resin in sequence. The procedure was then applied to fractionate water samples obtained at various sampling locations throughout two surface water treatment plants (WTPs) in central New Jersey to study its effectiveness, DOM occurrence, and variation along treatment units. The treatment plants utilize different treatment methods, hence producing variability in DOM fractions suitable for examining the procedure’s effectiveness. This procedure was compared with current fractionation protocols and proved to be accurate in fractionation of low DOM water.
