1. Introduction
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 flocculation 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 addition,
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, XAD-7 accumulation and GC/MS analyzing were used as method, and methanol – acetone mixed liquor
instead of single solvent as extract solution. Composition and hazard of organic pollutants in drinking
water were studied. Meanwhile, the organic pollutants absorption effects of three adsorbents, activated
carbon, haydite and quartz sand, were compared and discussed. At last, some useful advices were raised.
