Abstract	Liquid chromatographic method and micellar electrokinetic chromatographic method were optimized for determination of atrazine, desethylatrazine, desisopropylatrazine, hydroxyatrazine and their polar degradation products in solutions with humic acid without previous sample preparation step. Reversed-phase HPLC method was satisfactory in terms of repeatability and detection limits, which were ± 1.7–12.5% (RSD) and 0.1–0.5 mg L−1, respectively. However, the most polar products could not be separated from the front peak pertaining to humic acid. With MEKC, excellent separation of both chloro and hydroxy degradation products and parent compounds was achieved in a single analysis, and possible interferences of humic acid were successfully avoided by its retention at the anode. Drawbacks were detection limits, estimated to be 2–4 mg L−1, and RSD of the migration times was 20% compared to 0.5% with HPLC method. HPLC method was used to monitor degradation of atrazine and its first degradation products in the presence of humic acids, and MEKC was used for confirmation purposes.
