This report describes the development of a method for the determination of EDTA in water. The samples are concentrated on an anion-exchange resin, converted tot the corresponding ester with n-butanol/ acetylchloride and analuysed by gas chromatography equiped with a N/P detector. The standard addition method is suitable for the analysis of EDTA in drinking water. In surface water samples some difficulties with the quantificaiton occured, possibly caused by adsorption of EDTA on particles present in water and the high conductivity of the water. the accuracy of the method for surface water samples can be improved by increasing the number of additions. the analytical procedure is time consuming. Further investigations to improve the method are required.
