Determination of EDTA in Aqueous Medium

摘要

In this paper, an optimized spectrophotometric method for the determination of EDTA in aqueous medium has been developed at the wavelength of 535 nm, pH = 1 and reaction time of 20 min. The method is based on a discolorimetry reaction. The method has a detection limit of 38 ng/l. The proposed methodology for the determination of EDTA requires lower quantities of reagent and low reaction time as compared to other works.
