研究了天然有机物（NOM）存在和不存在时，原生颗粒活性炭（GAC）和预负载GAC对氯贝酸（CA）和异丙安替比林（PPZ）的吸附性能。尽管较低的log K-ow，PPZ显示出比具有羧基的CA更高的对GAC的选择性。在二元溶质体系中，CA和PPZ之间的吸附竞争降低了单个化合物在GAC上的吸附量。NOM存在下的吸附等温线数据表明，NOM在本体溶液中或预负载在GAC上可以显着降低吸附量的CA和PPZ的GAC。
Adsorption of clofibric acid (CA) and propyphenazone (PPZ) to virgin granular activated carbon (GAC) and preloaded GAC was evaluated in the absence or presence of natural organic matter (NOM). In spite of lower log K-ow, PPZ showed higher selectivity to GAC than CA, which has a carboxylic group. Adsorption competition between CA and PPZ in binary solutes system decreased the amount of individual compound adsorbed to GAC. Adsorption isotherm data obtained in the presence of NOM showed that NOM in bulk solution or preloaded on GAC could significantly reduce the amounts of CA and PPZ adsorbed to GAC.
