This report describes the development of a method for the determination of ethylenediaminetetraacetic aced (EDTA) in various types of water at low mug/L level. After a short sample pretreatment the sample is analyzed using reversedphase ion-pair liquid chromatography. UV absorbance detection is applied at 254 nm. The method is suitable to determine EDTA in surface water, bank filtrate, infiltrated water and fineshed drinking water. The method is simple (short sample pretreatment) and has a low limit of detection (0.8 mug/L). In general, the method provides calibration curves which have good regression characteristics (correlation coefficient > 0.999). 31 samples from several drinking water companies have been analyzed in order to determine the concentration of EDTA.
