English Abstract 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.
