The potential danger of organic pollutants to human body has caused a world-wide concern recently [1-
3]. Contents and kinds of trace organic pollutants in drinking water are increasing which will threaten
safety of drinking water [4]. POPs, which is a pollutant in water brought by human, especially causes
serious harms due to its poor biodegradability [5-6]. At present in the developed countries, drinking water
is treated mainly by flocculat ion and chlorination disinfection [7]. But unfortunately, these processes have
no effect on natural organic matter which has low molecular weight or low content [8-10]. In addit ion,
disinfection by-products after chlorination disinfection will cause a series of new problems [11-13].
Adsorption is widely used in contamination control in recent years due to its characteristics of low
costs and easy to operate [14-16]. It is also suitable for drinking water safety field because it has unique
advantages in trace organic pollutants removal with no secondary pollution [17]. In this study, XAD-4,
