摘要：

A semi-automatic coupled-column HPLC-method for the rapid determination of desethylatrazine, simazine, atrazine and terbuthylazine in drinking water was developed. Tenax TA was used as precolumn packing material. 100 ml of the water sample are percolated through the precolumn, on which the analytes are preconcentrated and prefractionated. After the HPLC-integrated sample processing the triazines are transferred to the series-connected analytical column, where separation and detection takes place. The method leads to detection limits between 15 and 32 ng/l. The recovery rates range from 46 to 96% in drinking water.
