摘要

The characteristics of the Danube river alluvial sediment are of great importance in assessing the risk for transport of pollutants to drinking water sources.Characterization of the sediment column layers has shown that the alluvial sediment,sampled near the city of Novi Sad,is a mesoporous sandy material with certain differences in the properties of individual layers.In order to investigate the sorption mechanisms of four chlorinated phenols (CPs) on the alluvial deposit,static sorption experiments were performed at pH 4,7 and 10.The results of sorption experiments,confirmed by principal components analysis sugest different mechanisms govern the sorption process at different pH conditions.This can be attributed to the molecular characteristics of CPs,geosorbent properties and to variations in the surface charge of the sorbent at different pH conditions.
